How transformations affect the mean and standard deviation

The top panel shows some data. You can move the points back and forth to see how the mean and standard deviation change. The top panel shows the same data, but transformed via the transformation X -> aX + b. You can change the values of a and b using the sliders and see what happens to the data, the mean, and the standard deviation.
