Statistical programs sometimes use special "flags" to draw attention to an unusual or unexpected outcome. When there are pages and pages of results, these flags facilitate the task of finding out if anything went awry, making it possible to quickly find areas in need of attention.

Lertap 5 has numerous flags particularly useful when it comes to assessing how item distractors have worked. Examples are presented in this paper.

It also has options which control how selected statistical indices are flagged -- for example, should a chi-square value be flagged when it reaches the .01 level, the .05, or .10? Options such as this are set in Lertap 5's "System" worksheet.
