Interactive Bell Curve


In probability theory, the bell curve (also known as the normal or Gaussian distribution), is a very common continuous probability distribtuion. This interactive bell curve was developed to help students in an elementary statistics course. The demo computes the z-score correspoding to a given cumulative distribution function value. Recall that the z-score is the signed number of standard deviations by which an observation or data is above the mean.
