Q) WHICH FORMULA SHOULD BE USED TO CALCULATE VARIANCE?

ANSWER)

We know that there are 2 types of variance, Population variance and sample variance. As in this question, we are considering all the values of the data to find variance. we'll find Population Variance. If we would considered only some values (sample) from the data (population), we would have considered to find sample variance.

Population Variance is given as sigma squared which is calculated by sum of square variables minus mean, divided by number of observation in population.

$\sigma^2=\frac{\sum(x_i-\mu)^2}{N}$

which is represented by option C
