On the other hand, thick bins can conceal some of the interesting bumps in data. It will not be a mathematically precise formula, just a rule of thumb that make a smooth histogram likely on the first try. First, the student can load the penny data into the text area. Then the program reads the data to make a control panel. Then the student can adjust the control panel to make a graph.
Students can get a feel for how data analysis is accomplished.
Students may put either the mass or the year on the horizontal axis to view its distribution. All three factors may be set with the control panel. Lowering the maximum or raising the minimum will have the effect of removing some of the coins from the final distribution. Similarly, including only one mint instead of two or three will cut down on the amount of data that is graphed. These pages are very similar to the basic pages.
