Summary Statistics Source for Scale Variables

  1. Drag and drop the scale variable Hours per day watching TV to the left of Age category in the Rows area of the canvas pane.

    The first thing you may notice is that the Count and Column N % summaries have been replaced with Mean--and if you right-click Hours per day watching TV on the canvas pane, you'll see that it is now the summary statistics source variable. For a table with a scale variable, the scale variable is always the statistics source variable regardless of its nesting level or dimension, and the default summary statistic for scale variables is the mean.

  2. Drag and drop Hours per day watching TV from the Rows area into the Columns area above Get news from internet.
  3. Right-click Hours per day watching TV and select Summary Statistics from the pop-up menu. (It's still the statistics source variable even when you move it to a different dimension.)
  4. In the Summary Statistics dialog box, click the Format cell for the mean in the Display list and select nnnn from the Format drop-down list. (You may have to scroll up the list to find this choice.)
  5. In the Decimals cell, type 2.
  6. Click Apply to Selection.

    The table preview on the canvas pane now shows that the mean values will be displayed with two decimals.

  7. Click OK to create the table.
