What is Jensen's Inequality?

Jensen's Inequality relates the value of a convex (or concave) function at the weighted average of several numbers to the weighted average of the function values.

For a convex function, the function evaluated at the average is less than or equal to the average of the function values. For a concave function, the inequality is reversed.
