Abstract

A six-category test of biological background, consisting of terms, names of men, etc., was constructed. Three alternate forms, marked by the same key and of equal difficulty, according to an item analysis, were made. Correlation of odd and even items gave reliability coefficients of + .88 and + .90. Statistical analysis of 500 tests of college and high school students in the state showed significant differences, by analysis of variance, among the following groups: graduate students, juniors and seniors, freshmen and sophomores, and high school students. Norms are given for these groups. No significant differences were found among different comparable student groups throughout the state. An indication of the validity of the test is shown by a correlation of + .53 with the final examination of forty students in one physiology class. The test may be useful in sectioning large classes in biology and estimating aptitude in this area.
