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 the mean sensitive to a substantial change in the movable blue value?
Exterior Angles of Polygons
Click the "▶" button. Observe the angles turned by the car at the corners.
Drag the green points. Check the "Show Measurement" box to see the measurements of the angles.

1. What is a + b + c + d + e, the total angles turned by the car?
2. a, b, c, d, e are called the exterior angles of the convex pentagon.
In general, what is the sum of all exterior angles of a convex polygon?
3. How would you modify the result if the pentagon is NOT convex?
