Statistics (2D Histogram Plots)

Click the Statistics button in the Plot: Histogram options pane of the Graph Options dialog to display the Statistics dialog. Note that this dialog can also be displayed by clicking the OK button in the Add Legend dialog. Use the options in this dialog to include useful statistics in your graph by selecting the appropriate check boxes.

Plot. Although all of the options are the same for each plot, you can make changes to each plot independently of the other. Select here the plot to which you want to make changes. Note that this option is only available if the Statistics dialog has been displayed via the Insert - Statistics menu.

Shapiro Wilk Test. Select the Shapiro Wilk Test check box to include the Shapiro-Wilk W statistics for normality and its associated p-value in the plot.

Descriptive statistics. Select the Descriptive statistics check box to include a variety of descriptive statistics including the total count, mean, and standard deviation, as well as the minimum and maximum values in the plot.

Total Count. Select the Total Count check box to include the total count or number of cases used in creating the histogram in the plot.

Kolmogorov-Smirnov Test. Select the Kolmogorov-Smirnov Test check box to include the Kolmogorov-Smirnov d statistics (for normality), its associated p-value, and the Lilliefors statistic in the plot.

Note: If you do select statistic(s) to include in your plot, the Add Legend dialog will also be displayed, which is used to select where and how to attach the statistic(s) to the plot.

Value Format. Use the Value Format group box to select from a variety of number formats to use for the numeric values including General, Number, Date, Time, Scientific, Currency, Percentage, Fraction or Custom. Most of the options in this list have more than one representation, except the General and Percentage options. Some options also allow you to specify decimal information.
