How do I find the variance for a sample of 15
Numbers given are 52,70,50,61,49,46,48,55,47,68,61,70,71 and 69
Here a sample of 14 data points are given it was mentioned as 15 in question. We need to compute the variance of the sample and we consider n = 14 as only 14 data points are given.
Variance of a sample is calculated by the following formula.
