View data distribution

In “variables view window”, click the variable name in the middle panel (variables name list), view that variable’s data distribution in the right panel.  If the variable is a continuous variable, its min, max, mean, sd, and 5%, 10%, 25%, 50%, 75%, 90% and 95% percentiles will be listed as well as horizontal “*” bars to show the histogram (shape) of the distribution; if it is a categorical variable, its discretionary coding (category) and frequency for each category will be shown as well as horizontal “*” bars graph to show the distribution.

In “analysis design window”, right click the variable name in the right panel (variables name list), select “View data distribution” from the popup menu.  A new window showing the selected variable’s distribution will pop up.

Treat a categorical variable as a continuous

Empower determines that a variable is either categorical or continuous based on number of discrete values of that variable in the data file. If the number of discrete values more than 20 and the values are numeric, it is treated as a continuous variable, otherwise, the variable will be treated as categorical. 

If a variable is treated as categorical by Empower and you want to change it to continuous, right click on the variable, select “Edit label” in the popup menu, in the “Input labels” window (see below), check “Treat as continuous variable” and click “Save -> Exit”.  If you want to change it back, repeat the above steps. In the “Input labels” window and check “Treat as categorical variable”.
