Introduction

Here in above scenario we have to calculate mean, variance and standard deviation.

Mean : Mean is one of the measure of central tendency. it is most widely used central tendency.

           It is nothing but average of given set of data.

 

 In statistics, the two most crucial measures are variance and standard deviation.  Standard deviation is a measure of the distribution of statistical data, whereas variance is a 

measure of how data points differ from the mean.
