Passage

Instructions for questions below: Read the following paragraph and answer the five questions which follow:

An educational psychologist wanted to develop an achievement test in physics for graduate students. After going through the usual test construction procedure, he retained 100 items; each item having five alternatives, one of them being correct. The psychologist wanted to examine the factor structure of the resulting achievement test. Using a sample of 1,000 subjects, the psychologist obtained the inter-item correlations. He obtained the initial estimates of communality and then decided to factor analyze the inter-item correlations matrix by following the common-factor model. He extracted the unrotated factors and retained the first nine factors for rotation. The nine unrotated factors explained 67.5 percent of variance. After factor rotation, all the inter-factor correlations were found to be zero. The factor structure of the achievement test of physics was found to be interpretable.
