INTRODUCTION
The term financial statistics is related with all the numerical figures, data and values
which helps in summarizing relevant as well as appropriate information. Data as gathered with
the help of different statistical means is required to be evaluated with the help of the best tools
and methods for deriving proper interpretation from it. The present report is related with the use
of different statistical tools for assessing results out of it. This report will help in assessing
earnings of both the men and women of public & private sector with the help of hypothesis
made. Also, various charts and graphs will be presented for supporting such table made.
Furthermore, analysis of hourly pay rate in different region of UK will be provided. Also,
explanation related to economic order quantity along with requisite calculations made. At last the
report will also shed light on designing of both the bar and pie chart for supporting data of
different streets.

Interpretation : It can be interpreted from the above table that the p value of two tail are
1.35 which is greater than the value of .05. It indicates that there is no significance difference in
the earnings of men and women in public sector. So they did not require to take the alternative
hypothesis. There is no significance difference in earnings of two genders because of the various
reasons such as government support, legislative support, different policies etc. In public sector
government provide various facilities and equal opportunities to both men and women which
reduce the difference in their incomes (Peters, 2016). The t-test helps to determine the difference
in the annual income of men and women in public sector.

Interpretation : As per the above hypothesis it can be concluded that there is no
significance difference in the earnings of men and women in private sector. The p value of 2 tail
is 2.16 which is greater than .05 value. It shows no significance difference in the two variables of
men and women. In private sector, companies provide equal opportunities to their employees to
use their skills and knowledges and perform according to their job role. They also follow the
different legislation such as equal pay act, employment act etc. which help to provide equal
income to the men and women who work in their companies. The t-rest help to confirm the result
by providing the different hypothesis and test them to get accurate and reliable result.

Median : it refers to the middle value of the series. If the number of the data are even
than it can be calculated as dividing the total no. of data to the value 2 and of the series id odd
than it can be calculated by adding to middle value and then divide it by 2 (Konik and et.al.,
2019). It helps to determine the average of the value.
Median for the frequency distribution series can be calculated in two ways such as :
1. Divide last cumulative frequency to the value 2.
= N / 2
2. Insert the formula
= L / 2 + H / f [N / 2 – C]
L = lower limit of the median class
H = Size of the class
F = Corresponding frequency of median class
N = summation of all the frequency
C = Cumulative frequency just before to the median class of the series
As per the above table median of the data are :

= 14.13
Quartile : It divides the series into 3 part such as 1 quartile, 2 quartile and 3 quartile. 1
quartile present 25% of the series while 3 Quartile present 75% of series value. The interquartile
range refers to the difference between the 3 quartile and 1 quartile. Interquartile range value help
to identify the value which belongs to outlier.

Mean : It is used to present the average value of the data. In simple term it can be
obtained by dividing the sum of value to the total number of value. It can be calculated by
different methods such as direct method, indirect method and shortcut method or step deviation
method (Arithmetic Mean, 2018).

Calculation of standard deviation
Standard deviation : It is used to interpret the relation with the average or arithmetic
number. In simple term it present the deviation of value from the average. If the standard
deviation is low than the spread from the mean is minimum but if the standard deviation is
higher than the deviation or spread from the average is high (Statistics - Standard Deviation of
Discrete Data Series, 2019).

Interpretation : It can be interpreted from the above table that the standard deviation of
the data is 10.15 which indicate that the earnings of the staff is highly deviates from the average
value.

Interpretation – From the above calculation it has been analysed that the firm is engaged
in the business of filling in more oil as compared to the capacity of the bottle. In terms of
probability, it can be said that 20% chances are there that the firm is providing more oil than the
bottle capacity as defined by the standard norms. The actual capacity of the bottle containing
olive oil is 200 ml which is provided by the firm. The average value obtained by the firm is 202
ml by making use of relevant statistical methods. Also, the standard deviation of the firm
determined is 2.4 ml. Thus, it can be evaluated that the firm has done breach of all the applicable
EU regulations. Non compliance has been made by the firm in respect of fulfilling of more olive

Interpretation – From the above calculation it has been analysed that the firm is engaged
in the business of filling in more oil as compared to the capacity of the bottle. In terms of
probability, it can be said that 20% chances are there that the firm is providing more oil than the
bottle capacity as defined by the standard norms. The actual capacity of the bottle containing
olive oil is 200 ml which is provided by the firm. The average value obtained by the firm is 202
ml by making use of relevant statistical methods. Also, the standard deviation of the firm
determined is 2.4 ml. Thus, it can be evaluated that the firm has done breach of all the applicable
EU regulations. Non compliance has been made by the firm in respect of fulfilling of more olive
oil in the bottle as per the defined and prescribed limits of the bottle (Moses and Venkatachalam,
2016). Thus, it is duty of the firm to ensure that the management is making compliance of all the
applicable rules, regulations and standards while undertaking the function of olive oil filling in
the packaging bottle which has not been met by the firm as a result of which it has accounted for
breach of the EU regulations.

Interpretation – With the help of economic order quantity, every business firm can make
improvement in their profitability as well as productivity level. It has been defined as one of the
most suitable as well as ideal order quantity which every business organisation should place in
case of inventory refilling. By making economic order, it helps the firm in minimizing its
unnecessary cost expenses as associated with its production function including holding, storage
and ordering cost (Miah, 2016). From the above table it can be interpreted that the supplier is
required to make order of 2683.28 units from the perspective of minimizing total inventory cost
and economical order. Thus, it will be considered as profitable for supplier to place inventory
order of 2683.28 units with the storage cost of £0.5 and cost price of £2 for maintaining
inventory level and reducing cost expenses.

Interpretation – By using bar chart, one can display given data set in form of bars. It
helps in representing data of the project in the form of horizontal segments with both the
variables in proportion of each other (Chandrasekaran and Umaparvathi, 2016). As per the above
charts, it helps presenting data i.e. number of bedrooms in different areas.
2. Pie chart
The term pie chart basically is a type of statistical graph which helps in providing
detailed explanation about all the types of numerical data set (Alan, 2016). With the help of
statistical graph, it helps in displaying relevant data set by making detailed bifurcation of it in to
different parts i.e. in a circular graph form.
