In this c program we are taking the values for a set from the users the mean is calculated by taking average of the sum by using a for loop. Lets plot this on the chart. First calculate the sample mean.
To calculate the variance in a dataset we first need to find the difference between each individual value and the mean.
Divide the result by the total number of observations N. Population variance is given by sigma2. Standard deviation is the measure of how far the data is spread from the mean and population variance for the set measures how the points are spread out from the mean. Find the squared difference from the mean for each data value.
