Results of a subtest of the Project Access battery, comparing the influence of race, sex and city on inductive reasoning items, are presented. The participating Junior High students represented three racial groups, Black, White, and Mexican Americans, from three cities, Los Angeles, Memphis, and Washington, D. C. The test, entitled Letter Groups, contained 25 vowel/consonant items instructing the student to find the rule which related four of a set of five to each other. The correct answer was a single unrelated set. Results indicated that the majority group (Whites) fared better than did the minority groups (Mexican Americans or Blacks); comparisons by city, whether between race or within race, indicated the best performing group was the Memphis Whites, and the second best the D. C. Blacks; and comparisons by sex indicated close performance patterns between males and females, but wherever significant differences did occur, it was the female who was favored. (Author/LS)
