To learn what the value of the standard deviation of a data set implies about how the data scatter away from the mean as described by the empirical rule and chebyshev’s theorem.

Web On The Assumption That The Actual Population Mean Is 38, 500 Miles And The Actual Population Standard Deviation Is 2, 500 Miles, Find The Probability That The Sample Mean Will Be Less Than 36, 000 Miles.

It is calculated by taking the average of squared deviations from the mean. Web standard deviation tells us the variability of a data set in several applications, including: Subtract the mean from each data point. Smaller values indicate that the data points cluster closer to the mean—the values in the dataset are relatively consistent.
