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]?

Chaos Game

Creates an image based on the Chaos Game [url=http://en.wikipedia.org/wiki/Chaos_game]wikipedia[/url] [url=http://mathworld.wolfram.com/ChaosGame.html]Wolfram[/url][br]It takes a random point in the polygon and then translates it by a fixed fraction of the distance to one of the vertices chosen at random. This iteration is repeated.[br]Sides gives the number of sides in the polygon[br]Points is the number of points per iteration[br]Fraction sets the fraction[br]Speed adjusts the animation speed[br]The default settings produce the Sierpinski Triangle
