Explanation:
Detailed explanation-1: -Calculate the Sample Standard Deviation Calculate the mean or average of each data set. To do this, add up all the numbers in a data set and divide by the total number of pieces of data. For example, if you have four numbers in a data set, divide the sum by four.
Detailed explanation-2: -First we sum the values, then divide by the number of observations to calculate the mean. Then we subtract the mean from each of the observed values. These values are squared and summed to calculate the standard deviation and the standard deviation of the mean.
Detailed explanation-3: -The standard deviation for the scores 1, 2, 3, 4, 5, 6 and 7 is 2.
