Quizplus · Accepted Answer

The sample standard deviation is calculated by taking the square root of the variance. First, find the mean: (13 + 14 + 15 + 16 + 17) / 5 = 15. Then, calculate each deviation from the mean, square it, and find the average of those squares (variance). Finally, take the square root of the variance. The calculations give a standard deviation of approximately 1.58, which rounds to 1.6.
