Workspace Node: Frequency Tables - Results - Descriptives Tab

In the Frequency Tables node dialog box, under the Results heading, select the Descriptives tab to access the following options.

Element Name Description
Descriptive statistics Select this check box to produce a spreadsheet of descriptive statistics for the selected variables. Note that the manner in which data are processed in the computation of descriptive statistics depends on the Categorization method for tables & graphs (see the Advanced tab). Specifically:
  1. When the Step size option button is selected and a user-specified minimum is specified, all cases with values less than the minimum will be ignored;
  2. When the Integer categories option button is selected, all non-integer values will be ignored;
  3. When the Specific grouping codes (values) option button is selected, all values that do not match any of the selected integer codes will be ignored;
  4. When the User-specified categories option button is selected, the Descriptive statistics button will be unavailable (because complex compound conditions can be specified to assign cases to categories, which could result in a case being eligible for more than one category). A case will be assigned to the first User-specified interval to which it "fits" and Descriptive statistics will not be calculated for these intervals (see also Define Categories).

In all cases, missing data will either by deleted casewise or pairwise, depending on the selection in the MD deletion group box.

Box & whisker plot for all variables (1) Select this check box to produce a box and whisker plot for the selected variables. The box and whisker plot will summarize each variable by three components:
  1. A central line to indicate central tendency or location;
  2. A box to indicate variability around this central tendency;
  3. Whiskers around the box to indicate the range of the variable.

The Results - Box-Whisker Type tab contains options to specify a box and whisker type plot.

Normal probability plots (2) Select this check box to produce a cascade of normal probability plots for the selected variables, one plot per selected variable. For more information on how the standard normal probability plot is constructed, see Normal Probability Plots.
Half-normal probability plots (3) Select this check box to produce a cascade of half-normal probability plots for the selected variables, one plot per selected variable. For more information on how the half-normal probability plot is constructed, see Half-Normal Probability Plots.
Detrended normal probability plots (4) Select this check box to produce a cascade of detrended normal probability plots for the selected variables, one plot per selected variable. For more information on how the detrended normal probability plot is constructed, see Detrended Normal Probability Plots.
3D histograms, bivariate distributions (5) Select this check box to produce a cascade of 3D histograms for selected pairs of variables, one plot per pair. A standard variable selection dialog box will be displayed, in which you select two lists of variables (from among those originally selected). 3D histograms will be produced for each variable in the first list with each variable in the second list.
