a statistic is chosen, the variable displays the statistic after its name in the Data field of the
Analyze dialog.
To calculate more than one statistic for the same variable, add that variable to the Data list more
than once. For example, to calculate the count, mean, and standard deviation for a variable, drag
and drop the variable from the Variable’s list to the Data list three times. Change one occurrence
to Count and one to StdDevP (one occurrence will already be Mean by default).
5.3.5.2 Bin a Variable
It is possible to group or, bin, a variable in an analysis. For example, when creating a distribution
of response times it may be beneficial to bin reaction times by groups of 100 milliseconds. Any
numeric variable in either the Rows or Columns list of the Analyze dialog may be binned by
double clicking the variable to display the Bin dialog. In the Bin dialog, enter an integer from 1 to
32,767 and click the OK button. Binning the variable by 1 is equivalent to not binning it at all. A
variable binned by more than 1 will display its bin number after its name.
