## Passage

A psychologist wanted to develop a numerical ability test for the student population. She wrote eighty multiple choice items, each item with five alternatives. The item analysis was carried out by finding discrimination index and item-remainder correlation for each item. Sixty items were retained in item analysis.

The new version, with finally retained sixty items was administered to a new sample (N = 400) twice with a time gap of eight weeks. The test-retest correlation was found to be 0.22, significant at. 01 level. The data obtained at the first administration of the sixty item version was also used for computing split-half reliability. The correlation between scores based on odd items and the scores based on even items was found to be 0.60. The split-half reliability coefficient was obtained after applying Spearman-Brown correction.

The scores obtained by the students were correlated with their marks in Mathematics in their annual examination which took place three months after the data collection. The product-moment correlation of 0.6 was obtained between test scores and mathematics. Norms were developed for the test. The normative sample yielded a mean of 40 and standard deviation of 8. The data were found to be normally distributed. As norms, percentile ranks were obtained.
