One of the most important things that we observe and apply in our day to day activities is statistics which itself is both science and art as well. When doing a study on “Comparative Statistical Analysis on PRAN Foods Limited and Akij Foods and Beverage Limited on Customer Satisfaction in the University Area”, we have used many of statistical techniques like mean, median, mode, 1st quartile, 3rd quartile, standard deviation, mean deviation, coefficient of variation Pearson’s coefficient of skewness, software coefficient of skewness, coefficient of correlation, coefficient of determination, and regression analysis. The main objective of this study is to find out whether PRAN Foods Limited or Akij Foods and Beverage Limited has a better performance in customer satisfaction in the Dhaka University Area. All these statistical techniques have been used to measure the independent variable X shown as sales and the dependent variable Y shown as profits in this report to find necessary interrelations between them.

divided by the number of values.
• For ungrouped data:
• For grouped data:
Median: The median of a data set is the value in the middle when the
data items are arranged in ascending order or descending order.
For ungrouped data:
For odd number of observations .
Here, n = number of observation

6. Measure of Location (cont’d)
For even number of observation
For grouped data:
• Mode: The mode is the value that occurs often in a set of data.
For grouped data:

7. Measure of Dispersion
• Mean Deviation: Mean deviation is the arithmetic mean of
the absolute value of the deviations from the arithmetic mean.
• Variance: Variance is the arithmetic mean of the squared
deviations from the mean.
• Standard Deviation: Standard deviation is the square root of
the variance.

8. Measure of Dispersion (cont’d)
• Coefficient of Variation: The coefficient of variation
represents the ratio of the standard deviation to the mean, and it
is a useful statistic for comparing the degree of variation from
one data series to another, even if the means are drastically
different from each other.
• Quartiles: Quartiles divide a set of observations into four equal
parts.
Quartiles Descriptions
First quartile 25% of the observations occur bellow Q1
Second quartile 50% of the observations occur bellow Q2
Third quartile 75% of the observations occur bellow Q3

9. Correlation & Regression
• Coefficient of correlation : coefficient of correlation is a measure
of the strength of the linear relationship between two variable.
• Coefficient of determination: The coefficient of determination is
the fraction of the variation in one variable that is explained by the
variation in the other variable.
• Regression equation: Regression equation expresses the linear
relationship between two variables.
