Module 2c Activity

At the end of the Module 2c slides, I presented an example of two sets of data representing two separate variables where the mean of both sets of data equals 7.5 and the standard deviation of both sets of data equals 2.0. Below I've pasted the box plots for those two sets of data. 

This is an illustration of how knowing the mean and standard deviation does not always give the best sense of center and spread. Why are the mean and standard deviation not the appropriate measures of center and spread in this case and how can you tell that by looking at the box plots?
