Table 45 Person measures after each item |
Table 45 shows the measures and fit statistics for the persons after the administration of each item, starting with the first item. This is useful for tracking how the person measures change as the items are administered. The item difficulties are based on all the items and persons. If items are deleted or selected in the "Specification" menu box , then the person measures are estimated only on the active items. The final measures in Table/Plot 45 will differ from the reported measures in Table 18.
