Passage
A psychometrician wanted to develop a new test of Abstract Thinking. He prepared eighty items, presumably assessing abstract thinking. Each item had five alternatives answers, one of them being correct. The psychometrician carried out item analysis by using itemremainder correlations. Item analysis retained sixty items. To examine internal consistency among the items, interitem correlations were inspected. Then the splithalf reliability coefficient, Kuder  Richardson reliability coefficient, and Cronbach’s alpha coefficient were obtained for the sixty item test. The analysis yielded the Cronbach’s alpha coefficient of 0.90. Since the test was fairly long and the alpha coefficient was also quite high, an attempt was made to develop two short versions of equal length by randomly dividing the test items. The 60 item version was, then, correlated with the already established abstract reasoning test, using N = 500. The correlation between the new and an established test was 0.24, significant at. 01 level.
