NI= number of items = (required) |
NI= is the total number of items to be read in (including those to be deleted by IDFILE= etc.). The maximum value of NI= is about 65,000 for one column responses or about 32,500 for two column responses in the standard program. NI= is usually the length of your test (or the total number of items in all test forms to be combined into one analysis).
Example: If there are 230 items in your test, enter
NI=230 ; 230 items
It is easy to miscount the NI= column. Scroll to the top of the Winsteps screen and check column positions:
