Quizplus · Accepted Answer

The sample standard deviation is calculated by finding the square root of the variance. First, find the mean of the data set, then calculate the squared differences from the mean, find the average of those squared differences (variance), and finally take the square root. The correct standard deviation for this data set is approximately 25.8.
