Why this chapter matters

In the 11 December 2022 Vice Principal paper, this chapter's territory supplied roughly 15 of the ~36 measurement questions — about 37 marks. It included the paper's most computational cluster: a full item-analysis table from which three consecutive questions (difficulty index, discrimination index, and item judgement) were asked using the upper/lower 27% groups.

It also owns the most repeated "concept-identification" items in this exam family: which is NOT a projective technique, the order of the affective domain, norm- vs criterion-referenced interpretation, and sociometry.

Chapters 1 (foundations) and 3 (statistics) complete the measurement block.
