![]() Sample Standard Deviation Formula – Example #2 So if you see here, although both the data sets have the same mean value, B has a more standard deviation than A, which means that data points of B are more dispersed than A. Sample Standard Deviation is calculated using the formula given below Similarly, calculate it for data set B also.Ĭalculate the square of the difference for both the data sets A and B. Similarly, calculate for all the data set of A. Now, we need to calculate the difference between the data points and the mean value. Calculate the Sample Standard Deviation for the data set A & B. Let’s say we have two sample data sets, A & B, and each contains 20 random data points and have the same mean.
