Issue/Introduction
How to specify whether a variable is continuous, categorical, or ordinal?
Resolution
1.Double-click on the variable header to display the Variable specifications dialog.
2.Under Measurement Type , select from a drop down list. Measurement types will map directly to subsequent analyses and graphs, identifying appropriate variables in each case (e.g., variables of type Categorical will be present within the list of categorical predictors available in a Factorial ANOVA).
Note that one can also define a variable as Unspecified, in which case no distinction will be made about the measurement type of the variable. One can also define a variable as Auto, in which case Statistica will automatically determine the measurement type of the variable based on the values of the variable.
