Extracting Variables from a Large Data Set

The data set extraction dialog allows you to create a new data set consisting of only the variables that you intend to use. This is useful because the program runs faster with fewer variables in the data set.

To create an extract data set,drag the variables that you would like to keep from the "variables" window in the main AM screen to the "VARIABLES" window in the extract dialog.

If you want to extract tests or subtests, first click on the "Tests" tab on the main AM window, then drag the tests or subtests that you would like to keep to the "TESTS" window of the extract dialog.

When you have selected all of the variables that you would like to keep, simply press the "Create Extract" button to pull the required data into AM.

Please note that the extract data set is only temporary unless you select "save" from the file menu.
