AQR Section 17: Where's the Mean?

This applet is designed for use with AQR Section 17. For each box-and-whisker plot below, drag the red point to where you think the mean of the data set is located. Click on the "Check the Means" button to confirm. Click on the "New Box Plots" button to create two new box-and-whisker plots.
Is there any way to tell which side of the median the mean will be located on?
