INTRODUCTION
Statistical is described the average of data that is helpful to conclude the central tendency
of the information in data range. It is consider to be a mathematical tool that is used to gather,
present, calculate and interpret of available data to find the best result (Groumpos, 2015). In
general the result are known ad the mean of the data. With the help of statistical tool many
businesses are beneficial to make effective qualitative and quantitative decision. This tool is used
by almost every department of economy like, government, business and individual that support
to determine the different factors like consumer price index, deflation etc.
In this project report, calculation of business and economic data is presented by preparing
different types of charts that help to express finding. There are various kind of statistical method
that help to ascertain result and plays crucial role in business planning that are discussed in this
project. Report also focus to evaluate of different business and economic data.

1. Calculation and evaluation of economic and business data.
Data or information is the raw or unorganized form that is used to represent objective,
ideas and condition of various ranges. In business the manager record data in order to evaluate
the performance of operation or other related activity. Data is basically exits in two form
qualitative and quantitative that is limitless and present everywhere. Measurement scales or data
have different types that help to categorise various kind of variable. Some types are categorical
data that use to represent characteristics such as People's language, age, gender etc. Nominal
Data that describe the separate units to label variables which have no numeric value. Where as
ordinal data shows the ordered and discrete units. Qualitative data comprise the useful
information about features and qualities data range, so it is not easy to calculate quality
information in figures (Asante and Armstrong, 2012). On the other side quantitative data deals
with information related to quantitative that can be evaluate in order to make future plans.
A & B) Different type of price index.
CPI (Consumer price index):
In general, the Consumer price index is a tool that is used to analyse the weighted
average of different kind of product for a number of customer. For example the price of
transportation, medical and food items. The CPI is calculated by considering changing price of

every items in the predefined types of product. It is very common that alternation in CPI are
used to measure price changes linked with the cost of living. In order to identify the period of
deflation and inflation in economy, CPI statistical tool is used more frequently. This tool is used
by numerous economist, government bodies, large companies and big institution for different
purposes. Such as, the economists uses CPI in order to determine the price of food items like
milk, bread etc. to analyse if there are changes in spending power of customer or not. As a result
thy advise either to expand or contract fiscal policy that help to make modification in price
index. The CPI has its importance to government and large companies also, as they are able to
measure the inflation and deflation within economy. This analysis help to make effective
decision by government (Lin and et. al., 2011). On the other side consumer price index housing
is also a part of CPI that is used to calculate the housing cost of owner occupied by them. In year
2018 august the consumer price index was 2.7% and in month July it was 2.5%. Similarly in year
2018 the CPIH during month of august was 2.4% and in July it was recorded as 2.3%. This was
observed that CPI and CPIH are declining year by year. The reason of decline was the continuity
decrease is the price of daily consumption good and services.

From the above presented chart it has been observed that there is non-stop fluctuations in
values of CPI year by year. As the value of CPI in year 2007 was 4.3, year 2010 it was 3.1 and in
2015 the value reduces to their most level at -1. It can be said that if the CPI shows the
increasing trend then it will have a good impact on the government but from customer point of
View it is Bad (Ichinose and Yamamoto, 2011).

From the above mention graph it was observed that CPIH in year 2007 was 2.4 that
increase up to 4.8 during year 2008. The CPIH shows uneven fluctuation throughout years and
was lowest in year 2015 with value 0.2.
RPI (Retail price index):
This index is used to scale the various income and price of different group. Retail price
index involves pension plans, sate benefits and different kind of allowances. This index displays
format of prices for typical good that help to figure out the actual changes in cost of living during
months during an accounting year. In general, government display the changes in price of
necessary items that are published on the monthly basis. This is helpful for household, to prepare
budgets (Gollier, 2011).

support to calculate the inflation. As it is seen that decreasing CPI lead to the inflation in country
and shows the percentage changes in the economy. It is observed that in year 2017 the CPI was
higher that CPI of 2016 by 1 value. Which shows the overall percentage change is 2% that gives
rise to inflation rate in economy.
E). Importance to have information about inflation.
Inflation is defines as the long term, rise in the price of product and services that is
happened because of regulation of currency (Inflation and price indices, 2018). It is a
quantitative measure of rate where the average price of selected good and services at a particular
time period. It is necessary for companies to have the exact understanding and knowledge of
inflation that support in formation of effective strategies to deal with inflation rate. Manager
must be knowledgable about inflation, which help to ascertain price of different product and
services accordingly. This support companies to be stable and sustainable in market.

between sales and average temperature. As it is noticed that when there is rise in temperature
than demand for hot drinks will automatically increase and vice versa. It is also observed that the
sales were equal to demand in 2nd and 4th week and in week 9 the sales were lowest because there
is sudden decline in temperature. Therefore it is concluded that scatter diagram display the
positive connection between the hot drink and temperature.
B. Determination of correlation and coefficient of determination.
Correlation coefficient defines as the statistical measure that is used to calculate the
capability and strength relation among the absolute movement of the two variable. The values of
coefficient are delimited by 1.0 on an implicit value ground or between -1.0 to 1.0. It is observed
that values of correlation coefficient are greater that 1.0 or less than -1.0 the result will be
incorrect. When the absolute correct correlation is -1 it is consider as negative, when values of 1
then there is positive correlation (Haimes, 2015). And if the correlation is 0 than it shows that
there is no connection among two variable. Basically this tool is used by large companies,
individual firms and also by government bodies that support to predict the future happing and
form effective strategies. Basic formula to evaluate the correlation coefficient that are described
below:
Calculation of correlation of coefficient:
Formula= N∑xy - (∑x) (∑y)/ √[N∑x2 - (∑x)2] [N∑y2- (∑y)2]
N – weeks in number
∑xy – Sum of average temperature and hot drinks
∑x - Sum of average temperatures
∑y - Sum of hot drink sale
∑x2 - Total of square of average temperatures
∑y2 - Total of square of hot drink sales.

Coefficient correlation 0.8
Determination of correlation 0.64
Coefficient determination:
The coefficient determination is related to the result that is derived from the examine of
regression. Basically it is said to be the square of correlation that is forecasted between y and x. it
is describe that higher coefficient of determination will be good indicator for the observation.
And if there is lower coefficient of determination than it is not consider good for observation.
Basic formula of determination is described underneath:
Formula: (Correlation coefficient)2
From the above table, the correlation coefficient is 0.8 and determination is 0.64. It is
observed that the result for both display a positive figure that are consider to be fit for the
observation.
C). Equations for prediction of sales for future time period.
Equation are consider very crucial that represent quantitative data for predicting the
upcoming sales of company (Herrera and Schipp, 2014). With the aid of equation manager of
companies are able to ascertain the future sales for product produced by them and create sales
plans accordingly. From the customer point of view the sales for a specific period with particular
temperature can be ascertained by following equation. Such as
Sales for Week A+ Sales for Week B/2.
Basic formula to form an equation is defined below:
FORMULA: Sales of closeness for higher temperature – Sales at higher achieved temperature *
difference between higher temperature and desirable temperature.
