Calculate the sample standard deviation for this data set: 88, 73, 91. The formula for the sample standard deviation is shown, where n represents the sample size, x represents each value in the data set, and x represents the sample mean. Σ(x-x) n-1 Step 1. Calculate the sample mean. Step 2. Calculate the deviations and the squares of the deviations. deviation of 88 = square of deviation of 88- deviation of 73 - square of deviation of 73
