AQR Section 17: Mean but Sensitive

The mean is a measure of center and [color=#0a971e]balance point[/color] for a distribution. Below is a distribution of 11 data points. Move the [color=#1551b5]blue point[/color] to see how the mean responds to changing this single value within the distribution.[br][br]Use the [b]New Data Set[/b] button, to try this action for several distributions.
Is the mean a [b]resistant measure[/b] of center for a distribution?[br]Is the mean sensitive to a substantial change in the movable [color=#1551b5]blue value[/color]?
