Which of the following statement/s is/are true about the item analysis ? (I) It involves qualitative analysis of test items (II) It improves the validity of the test. Codes :
Both (I) and (II)
Item analysis is the set of procedures used, after try-out of a test, to examine how each individual item performs so that weak items can be revised or discarded.
Statement (I) is true. Item analysis has a qualitative side (examining content validity, wording, clarity, bias and the plausibility of alternatives, often by expert judges) as well as a quantitative side (difficulty index, discrimination index, analysis of how each alternative is chosen).
Statement (II) is true. By retaining items with suitable difficulty and good discrimination, and removing unclear or non-functioning ones, item analysis raises the reliability and validity of the final test.
Both statements describe item analysis accurately.
Hence, the answer is Both (I) and (II).
