|Histogram Explorer is a tool for understanding histograms and their statistics. Drag the bars of the applet's histogram to see their effect on the mean, median, mode, range, standard deviation, and IQ, which recalculate after each change; select normal, uniform, symmetric, skewed left, skewed right, or random distributions. A "practice guessing" mode provides random histogram data, data entry boxes to guess the correct value for the centers or the spreads, and answers. The site also offers a free download of Histogram Explorer.|
