Passage

Read the following paragraph and answer the five questions which follow:

A researcher working in the area of human intelligence wanted to develop a new verbal test of intelligence. For this purpose, he wrote 200 objective multiple-choice items. Each item had four alternatives, one of which was right and the three remaining ones were wrong. He administered this initial version to a sample of 400 subjects. Using P27 and P73 as the cut-off points, he obtained two groups – Low Scoring and high scoring respectively. The item difficulty index and the item discrimination index were computed for 200 items. To assess whether each item significantly discriminates between Low scoring and High scoring groups, appropriate statistical significance tests were also employed. This item analysis process retained 150 items. The final version of 150 items was administered to a fresh sample of 750 subjects. The appropriate measures of internal consistency reliability were obtained. The test norms were developed using normalized T scores (mean = 100, SD = 20) and the Wechsler type deviation IQ scores. To assess the dimensionality of verbal intelligence, the researcher also carried out the factor analysis of item scores.
