The mean and standard deviation could be used. Both of the distributions are roughly symmetric, and only Campus B has an outlier of 37
minutes.
The mean and standard deviation could be used. Both of the distributions are roughly symmetric, and only Campus B has an outlier of 37 minutes.

The median and interquartile range could be used. Although there are no outliers, the distribution for Campus A is skewed left, and the distribution for Campus B is skewed right.
The median and interquartile range could be used. Although there are no outliers, the distribution for Campus A is skewed left, and the distribution for Campus B is skewed right.

The median and interquartile range could be used because the distribution for Campus A is skewed right with an outlier of 30
minutes, and the distribution for Campus B is roughly symmetric with no outliers.
The median and interquartile range could be used because the distribution for Campus A is skewed right with an outlier of 30 minutes, and the distribution for Campus B is roughly symmetric with no outliers.

The mean and standard deviation could be used because both of the distributions are roughly symmetric, and they do not have outliers.

Answer 1
