New York Yankee Roger Maris held the single-season home run record from 1961 until 1998. Here are Maris' home run counts for' his 10 years in the American League:

15 28 16 39 61 33 23 26 8 13

(a) Maris' mean number of home runs is x = 26.2. Find the standard deviation.

(b) Use your calculator to find the mean and standard deviation for the 9 observations that remain when you leave out the outlier. How does the outlier affect the values of x and s? Is s a resistant measure of spread?

x stands for mean & s stands for standard deviation.
