Directions: Instructions. Read the following paragraph and answer the five questions which follow.
A researcher working in the vocational interests surveyed different interest assessment tools and after a careful scrutiny selected 68 scales presumably covering all areas of vocational interests. He administered all these scales to a large sample (N = 750). The researcher correlated every scale with every other scale and obtained 68 × 68 correlation matrix. The 68 x 68 correlation matrix, without altering any of the diagonal elements, was factor analyzed and the unrotated factors were extracted. The Cattle's scree suggested 11 factors, where as Kaiser-Guttman's root ≥ 1 criterion suggested 14 factors for further rotation. The eleven factors explained 72 percent of variance. The eleven factors were varimax-rotated. After examining the results and discussion, the researcher decided to carry out the second-order factor analysis. He, therefore, re-rotated the eleven factors and found that some of the inter-factor correlations were fairly high. The second-order factor analysis suggested three second-order factors which were fairly interpretable.
Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R). Read the statements and choose the correct answer using the code given below.
Assertion (A) : In the above work, the researcher preferred Cattell's scree-plot over Kaiser-Guttman's root ≥ 1 criterion.
Reason (R) : Even with a small number of variables, Kaiser-Guttrnan's criterion always leads to the extraction of more factors, as compared to Cattell's scree.
