Extreme Data Points

Examine the effects of extreme data points on spread

Analyze each data set for extreme values. Then, find the standard deviation (sample) of the data sets. Finally, calculate the standard deviation of the data sets after removing extreme values.

\(1,\)\(5,\)\(9,\)\(1,\)\(8\)

Interpret differences in shape, center, and spread in the context of the data sets, accounting for possible effects of extreme data points (outliers).
