Answer 1

Data are collected about the amount of time, in minutes, each member of the lacrosse team spends practicing. How does a single outlier change the mean of the collected data?

A single outlier causes the value of the mean to move slightly toward the outlier.

A single outlier causes the value of the mean to move slightly away from the outlier.

A single outlier does not affect the value of the mean.

A single outlier doubles the value of the mean.

An outlier doesn't affect the value of the median of a set of data, but does affect the value of the mean. Depending upon your level of interest, you might want to invest a small set of data (say, 7 points) and experiment with changing the largest value. Does the mean change? Up or down?
