Question 1:
a) Significance of Population
Population is a fundamental part of existence. Population data is defined as the collection of
individuals or groups of individuals with common characteristics. Population is highly dependent
on geographic location, like all California residents or all of the United States. Demographics
(those that study the population) naturally classify this population. All living beings are
considered peoples (Kwak and Kim, 2017).
Geography is one of the many ways to define and study a population. Times, political
movements, religious beliefs or physical characteristics are how people are divided into different
societies. Population surveys are conducted by examining these heterogeneous numbers and
monitoring cross-sectional variables. For example, you might learn about the American
Republican population and see the population living in Texas. In this case, you can study where
these numbers are interconnected and learn about Republicans and Texas.
Significance of population data
Important decisions about a country, group or family are based on population data. Demographic
data includes a number of important details such as demographic information such as birth,
death, age, gender, annual income, occupation, language, etc. The overall socio-economic,
economic, political and cultural development of a country depends on population data (Kaur et
al, 2018)
The socio-psychological concept of population
Social psychology is the study of how people think, influence and relate to others. This happened
at the crossroads of psychology and sociology in the early 20th century. Psychology analyzes
human nature, while sociology studies the nature of society. On the other hand, social
psychology is the study of a person's personality and relationship with society. The field of social
psychology is social and the focus is on the individual. This is the study of personality in social
situations. This social situation can be the interaction of people, the interaction of a person to a
group, and the partnerships of a group with other groups. Social psychologists use scientific

3

methods to study how we perceive people and social events, how we influence and influence
others, social relationships and communication and group dynamics (Mishra et al, 2018).
Social psychology focuses on understanding the causes of social behavior and identifying the
factors that shape our feelings, behaviors and thoughts in social situations. Key hypothesis:
"Accurate and useful information on the most complex aspects of social behavior and thinking
can be obtained using basic scientific methods".
Population prediction method
The cohort component approach uses components of population change to predict population
growth. This tool assesses the population based on age group as well as other demographic
characteristics such as gender and ethnicity. This prediction method is based on the components
of demographic change, including pregnancy, mortality and migration.
To predict the total population and the number of males and females after the age of 5, find the
number of people who will or should be living in the future. Add the number of babies born and
the number of unique migrants to the surviving population. There are several ways to use the
cohort component approach. The method described here is easy to use and requires very little
demographic information (Majid, 2018).
b) Significance of sampling techniques
Definition: Sampling is a statistical approach that involves the selection of individual cases.
Helps to draw statistical conclusions about the population.
Probability Sampling Methods
1. Simple random sampling
In this situation everyone is completely chosen by some coincidence and everyone in the
population has the same chance, or probability, of being chosen. One way to give an irregular
example is to give a number to each person in a population and then use a table of irregular
numbers to choose which people should be included (Metelli et al, 2020).
2. Systematic sampling

People will be selected at normal times from the test pattern. The races are selected to ensure an
appropriate sample size. Effective routine monitoring is more useful than basic resolution tests
and is not difficult to monitor. In any case, it may encourage bias, for example if there are hidden
examples in the application for people in the analyst scheme, to the extent that the method of
analysis agrees with the timeliness of the underlying example (Symonds, Kattirtzi and
Shalashilin, 2018).
3. Stratified sampling
In this strategy, the population is initially segmented into subgroups (or strata) that all offer a
comparative brand. It is used when we can reasonably expect the amount of interest between the
different subgroups to change and we must ensure that the subgroups are represented (Tse et al,
2018).
4. Clustered sampling
In a collected example, subgroups of the population are used as test units, as opposed to humans.
The population is divided into subgroups, called aggregates, which are randomly selected to be
remembered for study. Groups are usually effectively identified, for example individual practices
or GP practices may be identified as groups (Amato et al, 2017).
Non-probability Sampling Methods
1. Convenience sampling
The accommodation test is perhaps the least sought-after method, as members are selected on the
basis of accessibility and ability to participate (Kim and Wang, 2019)
2. Quota sampling
This monitoring strategy is routinely used by economists. Users are given a set of preset topics to
try and list.
3. Judgment (or Purposive) Sampling
Also known as a specific or abstract study, this method relies on the scientist's judgment when
choosing who he wants to participate in. Analysts can then realistically choose a "representative"
test based on their needs or target people with specific characteristics. This approach is routinely

5

used by the media when seeking the general public for emotion and in thematic studies (Otzen
and Manterola, 2017).
4. Snowball sampling
This strategy is used consistently in sociology when studying hard-to-reach collections. Existing
subjects are asked to choose other familiar subjects, so the example is growing in size like a
moving snowball. It is possible to perform a snowball survey when it is difficult to identify a test
pattern. However, in selecting companions and co-workers of previously sought-after subjects,
there is a high risk of being overemphasized (selecting a very large number of people with
attributes or perspectives similar to the original one) (Sharma, 2017).
It is hard to conclude which sampling method is most reliable, because it’s mainly depends on
situation or researcher requirement. The type of sampling has to be chosen based on availability
of time, cost and research scope.
Question 2
1. Difference between primary and secondary data
Data collection plays an important role in the statistical study. Research uses a combination of
strategies to collect data and falls into two categories: critical information and optional
information. As the name suggests, essential information such as basic information is collected
by the unexpected scientist and supporting information is information that has been collected or
is now provided passed by another (Johnston, 2017).
A study uses a combination of methods to collect data that falls into two categories: primary data
and secondary data. As the name suggests, essential information is basic information collected
by the unexpected scientist and optional information is information that is currently collected or
passed on by another person. There are many differences between the essential and supporting
information described in this article. In any case, the main difference is that essential information
is authentic and unique and optional information is only a revision and translation of essential
information. While essential information is collected for purpose purposes, optional information
is collected for a variety of purposes (Sánchez-Llorens et al, 2019).

Primary data
Primary data is the data that was first obtained by researchers as a result of their direct efforts
and experience in solving their research problems. Direct data or raw data is also called.
Collecting basic data is expensive and requires resources such as investment and manpower, as
research is carried out by the organization or institution itself. The data is collected under the
direct direction and control of the researcher. Data can be collected through a variety of methods,
such as surveys, observations, physical examinations, postal questionnaires, completion and
survey questionnaires, personal interviews, telephone interviews, focus groups, case studies and
more (Flick, 2017).
Secondary data
It refers to the data collected by someone other than the user i.e. the data is already available and
analyzed by someone else. Common sources of secondary data include various published or
unpublished data, books, magazines, newspaper, trade journals etc.
Secondary data has many benefits because it is accessible and saves the researcher time and
money. However, because information is collected for purposes other than those considered,
there are disadvantages, so the usefulness of the data may be limited for a number of reasons,
including -into relevance and accuracy (Hox and Boeije, 2005).
The main differences between primary and secondary data are explained in the following
paragraphs.
1. The expression "essential information" alludes to the information that the analyst got first.
Optional information is information previously gathered by the specialists and control bodies.
2. Essential information is constant information and auxiliary information addresses the past.
3. Gather fundamental information to tackle a current issue and gather auxiliary information for
purposes other than the issue being settled.
4. Gathering fundamental information is a mind boggling measure. Then again, the auxiliary
information assortment measure is snappy and simple.

5. The primary wellsprings of information assortment incorporate studies, perceptions, tests,
surveys and individual meetings. In any case, government distributions, sites, books, magazine
articles, inside reports, and so forth They are different wellsprings of information assortment.
6. Building a great deal of assets takes a ton of assets, for example, time, cash and exertion.
Auxiliary information, then again, is generally modest and effectively open.
7. The essential information will consistently rely upon the requirements of the analyst and will
control the nature of the exploration. In any case, the auxiliary information are not identified
with the particular requirements or nature of the scientist (Cowton, 1998).
8. Essential information is given in crude configuration, while auxiliary information is essential
information in overhauled design. Optional information can be supposed to be gotten by
applying a factual strategy to essential information.
9. Information gathered from the essential source is more dependable and exact than the
auxiliary source.
Conclusion
As can be seen from the discussion above, raw data are original and unique data that researchers
have collected directly from the source according to their requirements. It's easy to access, but
has gone through a lot of statistical processing, unlike unorganized secondary data.
2. Advantages and disadvantages of primary and secondary
data
Unstructured data first collected by researchers is called primary data. The interpretation of the
primary data is largely a reference to the original and was originally created by the research
manager with a greater effort mainly to solve the "research".
Primary data collection appears to be expensive as the organizations involved are responsible for
collecting and analyzing baseline data. This data is just a secondary database obtained by
performing a series of statistical operations with this data (Rahman, 2020).
Usage data is used data that has undergone a series of statistical operations to obtain specific
information. These activities are unique and will save you time and effort. Secondary data is

collected from a variety of sources such as publications, internal business documents, accounts,
books, magazines, websites, and more. This data is called a reformed data format and has a lower
level of error and reliability than basic information (Cheng and Phillips, 2014).
Primary data
Advantages:
Solves specific research problems
Self-management can help identify and solve specific business problems. Collected information
is information that the researcher seeks to find and communicate in a way that is beneficial to the
particular situation in the organization (Karale, 2020).
Improved precision
Reference data is much more accurate because it is collected directly from a specific population
group.
A more significant level of control
Marketers have easy control over the design and research method. It also gives you a higher level
of control over information collection.
Real information
Basic market research is a good source of updated and updated information when collected
directly in the field in real time. Secondary data are usually less relevant and irrelevant.
Disadvantages:
More expensive
Collecting raw data can be very expensive as marketers or research teams need to start from
scratch. In other words, it is necessary to go through the whole training process and organize the
materials, processes, etc.

End-to-end research is a very long business. This is often much longer than the time it takes to
collect secondary data.
There can be many limitations.
Basic data is limited to a specific time, place or number of servers. For comparison purposes,
supporting data may be derived from other sources to provide more detailed information.
Not always possible
For example, a lot of studios may be too big for a company.
Secondary data
Advantages
1. The first advantage of using backup data (SD) is that it always saves time. Moreover, this fact
is evident in the so-called internet age. Before that, it took him hours to find a long library aisle
to gather supportive time. New technology has changed this world. The process has been
simplified. The exact information can be found through the search engines. The Allworth Library
has digitized its collections to allow students and researchers to conduct more advanced research.
2. Fair: In the past, SD was often restricted to individual libraries or institutions. It is not always
available to the public. The internet has been particularly remarkable in this regard. Internet
access is often the only requirement for accessibility. Sometimes you can get a lot of information
with just one click. But now the question is to make sure the information is correct (Vartanian,
2010).
Disadvantages
1. Data results: data collected alone (raw data) is collected from specific observations of the
mind. In this sense, secondary data sources can provide a great deal of information, but size
doesn't mean relevance. This is because it was collected to answer other research questions or
objectives. For example, the change could be due to data collected years ago. The information
refers to the whole country when trying to study a particular area, or vice versa, nationally, but
the information comes from the area.

Mode
In the given set of data, no turnover has been repeated over a period of 5 year; hence mode
cannot be calculated (Leys et al, 2013).
The mode is the most frequently displayed value in the data set. A data set can have one mode,
more than one mode, or none at all. Other popular measures of central tendency are the

Mode
In the given set of data, no turnover has been repeated over a period of 5 year; hence mode
cannot be calculated (Leys et al, 2013).
The mode is the most frequently displayed value in the data set. A data set can have one mode,
more than one mode, or none at all. Other popular measures of central tendency are the
established mean and the median of the mean (MacGillivray, 1981). The mode is the most as

The definition of standard deviation is a measure of the "spread" of a data value in a data set.
Spread refers to the degree to which a data value compares to the average value of the amount of
data. Variation is the square of the standard deviation (Wan et al, 2014). Variance and standard
deviation are indicators of variability. Measure the spread of data values in the mean by
specifying the standard deviation. If the standard deviation is large, there is a large dispersion in
the data values. This means that the values are farther from the average value. This means a big
change in the data set. The smaller the standard deviation, the less the data values in the data set
deviate from the mean. This means less variety and consistency (Ahn and Fessler, 2003).

Question 4
Importance of management information system in decision
making
Management Information System (MIS) has assumed a significant part in associations in the
course of recent years by giving instruments to producing data. It additionally assists supervisors
with settling on significant business choices (O'brien and Marakas, 2006). Activities in created
nations are dynamic and require data from all sources at all measure of time and in the most ideal
manner, utilizing the best data highlights conceivable. Business situations in India are changing
quickly on the whole regards and taking all things together zones with the assistance of cutting
edge programming apparatuses, for example, MIS, DSS and Expert System. MIS gives normal
data to help chiefs settle on choices dependent on information as opposed to presumptions.
Certain information and examination can assume an exceptionally valuable part in settling on the
correct choices about where and when to utilize human and different assets to play out your
association's central goal. Directors with great MIS can settle on choices from a cognizant point
of view instead of an immediate stance. This archive is an endeavor to plan and create MIS for
business associations, and shows how it can help you settle on administration choices identified
with the board capacities, particularly for senior heads (Al-Mamary, Shamsuddin and Abdul
Hamid, 2013).
Example 1: Honda is the world's largest manufacturer of discounted interior crucibles and
engines measured by size that typically generate over fourteen million internal combustion
engines each year. For Honda, getting the right kind of data is important in the current climate
that is not needed first, subsequent costs, better profits and greater benefits.
Example 2: Amazon, which began as an American multinational e-commerce company, has
grown to become a leading online retailer and provider of cloud computing services. The
incorporation of customer relationship management and information management into Amazon's
overall business strategy has been two technologies driving the company's growth. The business
stores customized information and buying trends of its customers in the customer experience
management module under enterprise resource management, which is combined with the
company's marketing and advertisement campaigns.

Example 3: Vodafone, like many other telecommunications firms, uses MIS to handle the billing
process, which was previously performed manually. These systems are mostly used to manage
networking components, provisioning facilities, and accounting billing. Call detail record (CDR)
or Station message detail recording (SMDR) is a file that contains all of the relevant details about
the time of the call, the origin of the call, call length, call fee, total use time in the billing period,
and the free minutes remaining in the billing period.
The significant part of the executive’s data frameworks in dynamic is:
Organization activity data
Settling on choices dependent on the information accessible in the administration data
framework mirrors the data created by the business. The board data frameworks arrange the
information created at the assignment level into a down to earth design. The board data
frameworks regularly contain information on deals, expenses, ventures and HR. In the event that
you need to know how much income your organization has acquired every year in the course of
recent years to settle on a choice, our administration data framework can furnish you with a
precise report with this data (Mason and Mitroff, 1973).
Script executable possibilities
The script execution feature is an important decision-making tool. This feature is included in
some managed information systems, while others provide the information needed to run scripts
in other applications, such as spreadsheets. If you decide in a certain way, what happens will
affect your decision. What-if scenarios show how various variables change as you make
decisions (Charnley et al, 2017).
Prediction to facilitate decision making
Each choice made will change your organization's normal outcomes and may require changing
your business system and by and large objectives. The administration data framework may have
pattern investigation or give data to play out this examination. A run of the mill business
methodology incorporates gauging all key operational results (Yu, Merigó and Xu, 2016).
Trend analysis can show you what these outcomes are in your current situation and how they will
change after making a decision. New values support a strategic strategy for the future.

Implementation and evaluation
When settling on choices with explicit objectives and supporting assumptions through
documentation and pattern examination of the board data frameworks, you need to follow
organization results to guarantee that they are going as arranged. The administration data
framework gives the data you need to decide if a choice has had the ideal impact or whether
restorative move ought to be made to accomplish the objective. On the off chance that you don't
get substantial outcomes, you can utilize the administration data framework to evaluate the
circumstance and make a further move if essential (Kochenderfer, 2015).
Quick access to information
Managers need quick access to information to make decisions on strategic, financial, marketing,
and operational issues. Businesses collect a lot of information, including customer registers, sales
data, and market research, financial reports, manufacturing information, and inventory and
personnel data. However, most of this information is stored in separate departmental databases,
making it difficult for decision makers to quickly access the information (Ackoff, 1967).
An easy data framework makes discovering data simpler and quicker by putting away
information in a focal area that can be gotten to over the organization. Thus, choices are made
quicker and all the more precisely (Laudon, 2007).
Choice dependent on the most recent data
The executive’s data frameworks incorporate information inside and outside the association. By
making an organization that interfaces a focal data set to inventory network retail locations,
merchants, and members, organizations can gather deals and creation information every day or
all the more frequently and settle on choices dependent on state-of-the-art data (Breiter and
Light, 2006).
Group can coordinate
In circumstances where gatherings and people are engaged with the dynamic interaction, the
utilization of oversaw data frameworks makes it simpler for gatherings to settle on joint choices.
For instance, oversaw of data framework in a venture group permits all individuals to get to a
similar basic information regardless of whether they work from various areas (Lunenburg, 2010).

Powerful translation of results
The executive’s data frameworks help leaders comprehend the outcomes of their choices. The
framework totals crude information into reports so chiefs can rapidly distinguish examples and
patterns that are not obvious in the first data.
Chiefs can likewise utilize the administration data framework to comprehend the expected effect
of the change. For instance, a project lead can run a framework recreation and pose a progression
of inquiries about "consider the possibility that a value exists" to foresee the effect of value
changes on deals (Bharati and Chaudhury, 2004).
Brief presentation
The administration data framework's announcing instruments empower chiefs to tailor reports to
various data needs. On the off chance that a choice requires the board endorsement, the leader
can create a concise synopsis for survey. In the event that your supervisor needs to share the
aftereffects of a definite report with associates, you can make a total report and give various
levels of extra information (Heilbrun, 1997).
Gazi and Hu (2015) distinguished different elements that impact the accomplishment of the
administration data framework to guarantee the achievement of the choice emotionally
supportive network, including framework quality, data quality, client fulfillment, and human
effect. The executive’s data frameworks are accounted for to have numerous advantages
regarding the help they give to improve the adequacy of the choice emotionally supportive
network. The fundamental part of an administration data framework starts with characterizing
the issue on which the last activity is based. Mintzberg (1976) referenced two significant zones
in the difficult definition stage. One of these territories, called "choice mindfulness", is
considered to trigger the choice help measure by distinguishing related issues, dangers, and so
forth The subsequent stage, known as "finding", is principally worried about examining and
exploring the issues and dangers recently recognized in "choice mindfulness". This is a
significant part of the way data the board frameworks work. Data has all the earmarks of being
basic to settling on the important choices that could influence the organization's future
objectives. Therefore, the part of data can be viewed as a beginning stage for dynamic. The
utilization of the board data frameworks is viewed as significant if the chief has a lot of data
