Abstract

Data from the 1948 administrations of the Law School Admissions Test (LSAT) are presented and discussed. Table 1 presents frequency distributions of total scores; means and standard deviations for all five 1948 administrations of the test; and the odd-even reliabilities of a spaced sample of 500 from the February 28th group for book 1, book 2, and books 1 and 2. Table 2 summarizes the principal statistics for the 10 sections of the test: 1) analogies, 2) sentence completion, 3) paragraphs, 4) word classification, 5) reading comprehension, 6) figure classification, 7) debate, 8) evidence contrary or irrelevant to a general statement, 9) reasoning and 10) reading. Tables 3 through 5 supply more detailed analyses of the test sections: frequency distributions of the biserial correlations in Table 3; frequency distributions of unequated deltas in Table 4; and information concerning the speededness of the test sections in Table 5. Section summaries and recommendations, evaluating each of the 10 sections in terms of biserial correlations, difficulty and speededness are also presented. (JGL)
