Posts tagged Cell Intervals

The choice of Cell Intervals (the number and width of the classes used to construct a histogram) can have an effect on the shape of the histogram. In general, a smaller number of intervals results in a less distinct shape, while a larger number of intervals can reveal unexpected patterns.
Note: Please refer to the other topic on cell intervals for more information about rules-of-thumb in regard to cell choices.

When constructing a histogram (a graph in which the classes are identified on the horizontal axis and the class frequencies are shown on the vertical axis by the heights of the vertical bars) it is important to choose an appropriate number of Cell Intervals (the grouping you will use to generate the classes for the histogram).
