Iteman’s interface is divided into three tabs.
- The Files tab specifies the files to be used: Data, Control, Output, and to specify the character code used in the Data Matrix to indicate omitted/skipped and not administered items.
- The Scoringtab enables you to perform scaled scoring and to perform dichotomous classification.
- The Output tab specifies options for the output. In addition, this tab is where you can request and set up a DIF analysis.
The Files Tab
To specify the Data and Control files on the Files tab (Figure 3.1), click the yellow button on the right for each file. This will activate a standard dialog window to specify the file.
Name your output file in the third box.
The fourth box, Report Title, allows you to name your Run. This will appear on the title page of the report output.
