  2. Now drag the bars of the histogram to see how it affects the statistics.
  3. From the Distributions menu (it's on the histogram window) choose a type of distribution.

Practice Guessing

This mode gives you a chance to guess the correct value for each statistic. Choose "Practice Guessing" from the Histogram Explorer's File menu. For each statistics selected a data entry box will appear. Two buttons will also appear at the bottom of the screen. After filling in a guess for each statistic click on the "Check Guesses" button.
