INTRODUCTION
Data mining is a kind of process which is used by organizations for data analysis, finding
pattern within large amount of data set and for various other kind of purposes. It has become one
of the most important part of an organization as it helps them in decision making, predict future
sales and for many other purposes (Unat and et. al., 2016). Data handing and business
intelligence methods are majorly used for analysing and extracting information from large
amount of data so that new data can be used for bringing changes within business strategies in
order to enhance revenue and profitability of organizations. Today it has become one of the most
important and effective part of an organization and is used in different ways in many industries
but mostly Business intelligence is used. Business intelligence is a kind of process, method or
technology that helps an organization to use, convert, analyse and extract meaningful data from
raw data which further helps an organization to expand their business and increase profitability.
For retail sector organizations it is extremely important for they need to develop strategies by
predicting their future sales on the basis of their current sales. This assignment will focus on
analysis of superstore data in order to identify and analyse sales and profit of the organization.
This assignment will also focus on conjunction in Weka Software of audidealership data with the
help of clustering and lastly advantages and disadvantage of Weka over Excel.
PART 1
By using data set of superstores analyse profit and sales over years and analyse it by using Excel
for pre- processing of data, also analyse and visualize the data
Data mining is majorly used for data handing and conducting business intelligence
operations. There are various kinds of methods that are used for data mining that comes under
data handing and business intelligence such as database systems, machine learning intersection
and statistics and many more. In order to transform data or extract useful information from it
there are many kinds of software’s or tools that can be used by organizations which helps
organizations to bring changes within their current strategies. Excel is one of those tools which is
based upon Data mining technique (Sajitha, Minimol and Mini, 2019). Mostly Excel is used by
organizations for financial calculation like calculation of their profit and sales, forecasting or
predicting future sales and for many other purposes. It is one of the most common data mining
tool which is used by organizations as it has various kinds of inbuilt functions that can be used
by organizations for data analysis. It can be used by organization to study many years past data

Data interpretation: By selecting only Technology from row label of pivot table above graph
can be generated. From the above graph it is clear that technology sales were highest in year
2009. From the graph it cannot be determined that profit was highest in year 2010 or 2012 but
from the table it can be clearly analysed that overall profit was highest in 2011
Demonstration of ways in which data can be practically analysed using Excel functions such as
Lookup, Pivot table, graphs and charts
Lookup Function: Lookup is an inbuilt function present in Excel, analysing and selecting a data
or value from current large se of data (Kaler and Gupta, 2017). It is available in reference
function in Excel. It can also be used for selection of values from different range. It can be used
to return a value from a pre-defined set of values or array. Syntax used for lookup is: Lookup
(lookup_value, lookup_vector, [result_vector])
For example: In order to identify sales generated from order id: 56581 lookup function can be
used:
=LOOKUP(56581,B2:B8400,F2:F8400)
=1121.84

2.2 explain data mining method that can be used in real business
In today’s era of large data set it is necessary to extract data in effective way so that relevant and
precise info is obtained. Thus, data mining is process of using large info to generate useful info
from it. It enables in finding out trends and new knowledge from it and taking relevant decision.
In order to do so there are various types of data mining tools and techniques which is available. It
depends in nature and type of data that which technique is suitable ( Kumar and Britto, 2019).
However, each technique is having a different process of analysing data. They are defined as
below
Tracking pattern- it is a technique in which is commonly used to review change in pattern of
data. This usually involves recognizing data of same abbreviations that may occur at regular

intervals or with change in flow of variables in particular time peri. Here, an example can be
taken of analysing sales of product on website.
Classification- it is a complex data mining technique in which data is classified is into several
factors and variable. This allows in drawing up further info from it. For example if data is to be
analyzed into customer income then it would be high, low and medium. The technique is used to
gather relevant info by classifying things.
Association- As name depicts it is a technique where data is analysed to view pattern. Here,
relationship is identified between variable and it makes it easy to show change in pattern. There
is high correlation between variable or pattern. For example, if customer buys specific item in
relation to other item.
Outer detection- this is a technique in which data analysis is done to fimd out any external factor
or anomalies within data. With that it becomes easy to find out why auch anomalies occurred.
This enables in better and effective understanding of audience.
Clustering- it is similar to classification but in this there cluster are made on basis of similar
characteristics or features and then data is extracted. There is change in things of how
Regression- basically it is used in planning and modelling but with this it enables in finding out
likelihood of variables due to existence of other. It shows that how any change in one factor can
impact of other. So, it is used in data set to find out relationship between two variables.
Prediction- this technique is used to predict future data. The use of this technique provide highly
useful and valuable data which can be used in future. Thus, here only by analysis historical data
and pattern, accurate prediction can be made into future. For instance, prediction is to be done of
sales in next year.
Thus, these are all data mining technique which can be used by business. This allows in
extraction of data and providing useful info Alongside, the info can be used to make strategy and
plans and also in taking decision. Moreover, technique make it easier to gain useful info there is
need to use proper and effective technique so that data is analysed precise and accurate. The
change in technique within real business is simple to do.
2.3 Discuss advantage and disadvantage of weka over excel
There are many types of technique available which is used in data mining. Apart from those, it is
required a software to run and implement those technique. Each technique works on different
platforms and contains many features. Along with it, connection between technique depends on

taken of analysing sales of product on website.
Classification- it is a complex data mining technique in which data is classified is into several
factors and variable. This allows in drawing up further info from it. For example if data is to be
analyzed into customer income then it would be high, low and medium. The technique is used to
gather relevant info by classifying things.
Association- As name depicts it is a technique where data is analysed to view pattern. Here,
relationship is identified between variable and it makes it easy to show change in pattern. There
is high correlation between variable or pattern. For example, if customer buys specific item in
relation to other item.
Outer detection- this is a technique in which data analysis is done to fimd out any external factor
or anomalies within data. With that it becomes easy to find out why auch anomalies occurred.
This enables in better and effective understanding of audience.
Clustering- it is similar to classification but in this there cluster are made on basis of similar
characteristics or features and then data is extracted. There is change in things of how
Regression- basically it is used in planning and modelling but with this it enables in finding out
likelihood of variables due to existence of other. It shows that how any change in one factor can
impact of other. So, it is used in data set to find out relationship between two variables.
Prediction- this technique is used to predict future data. The use of this technique provide highly
useful and valuable data which can be used in future. Thus, here only by analysis historical data
and pattern, accurate prediction can be made into future. For instance, prediction is to be done of
sales in next year.
Thus, these are all data mining technique which can be used by business. This allows in
extraction of data and providing useful info Alongside, the info can be used to make strategy and
plans and also in taking decision. Moreover, technique make it easier to gain useful info there is
need to use proper and effective technique so that data is analysed precise and accurate. The
change in technique within real business is simple to do.

what machine learning language is used by them. Here, a comparison is done between weka and
excel. There pros and cons are as follows
Weka – it is an open source software which uses Java as data mining tool. The software can be
run on Windows, IOS and Linux.
Advantage
Weka is known for its extensive machine learning capabilities as it supports all data mining
technique that are cluster, classification, etc
The access is granted with help of GUI
It can be connected with SQL
The technique uses decision tree, ID3, etc
It uses simple command line to handle large data set
Disadvantages
Only cluster analysis can be used in this
There may occur error in processing when there is large amount of data to be processed.
The memory of tool is less.
No connectivity with excel and other non Java based data base
Does not have the facility to save parameters for scaling to apply to future datasets.
Excel – It is a spreadsheet software offered by Microsoft Windows. The excel is highly flexible
and easy to use.
Advantage
It can be used for analysis as well as decision making.
The data can be viewed in easier way and on by sending to e mail or printing it.
There is no need to purchase or install excel in Windows.
The files in it are password protected which helps in maintaining of data
Th comparison can be easily done and pattern and trends is analysed properly
The data can be sorted and pivots table can be made
Disadvantage
It does not work on IOS, Linux and on other platforms.
Only creating one file may result in slow working of data.
The graph offered by excel is not of high quality.
It can not be connected with any other databases.

So, it can be evaluated that there are many new and advanced data mining technique which is
available. It has enabled in providing many features and running on various machine language.
Besides, weka can be connected with other databases but excel can not. Usually, it is necessary
to find out proper software which consists of various features. There are to be change in things.
Other than this, in terms of flexibility excel is easier to use as compared to weka.
CONCLUSION
From the above assignment it has been summarized that data mining is one of the most
important process which is required by the organizations to be focused on for prediction of
accurate results. Data mining helps in summarizing, analysing data so that on the basis of which
future strategies can be prepared. It can be used by retail sector organizations for prediction of
sales, profit so that organization can enhance their future sales and profit as well as their
relationship with their customers.
