AQR Section 17: Mean but Sensitive

The mean is a measure of center and balance point for a distribution. Below is a distribution of 11 data points. Move the blue point to see how the mean responds to changing this single value within the distribution. Use the New Data Set button, to try this action for several distributions. Is the mean a resistant measure of center for a distribution? Is sensitive to a substantial change in the movable blue value?
