Selecting variables

About

Before analyses can be performed, the variables to be used must be specified as the 'Y variables'. Where variables are to be compared, the second variable must be specified as the 'X variables'. The 'X variables' are also used when specifying the independent variables in a Multiple Linear Regression analysis.

Only Number and Code list variables will be available to select.

If more than one variable is selected OxonStat will automate multiple comparisons in one operation. See Performing multiple analyses for details.

Univariate tests

Each statistical test or graphics option presents a dialog with a variables panel at the top. For univariate test, or tests that consider a range of variables all at once, a single listbox of Y variables is provided:

Selecting multiple variables

In each of these lists you can select variables by using any of the standard Macintosh listbox selection methods:

Select a variable: Click on the variable.
Select multiple variables: Press and hold the Command key, then click the required variables (they don’t need to be next to each other).
Select multiple variables that are adjacent: Click the first variable you wish to select, then press the Shift key and click the last variable required. All variables in between are included in the selection.
You can also click first variable, press and hold the trackpad or mouse button, then drag over other variables.
Select all variables in a list: Click in the list to make it active, then press Command-A.
Deselect one item when multiple items are selected: Hold down the Command key and click the variable.

Actions in one list will not affect your selections in another list.
