An Investigation of the Robustness of the t Test to Unit of Analysis Violations.
Blair, R. Clifford; And Others
Educational and Psychological Measurement, v43 n1 p69-80 Spr 1983
Sampling experiments were used to assess the Type I error rates of the t test in situations where classes were randomly assigned to groups but analyses were carried out on individual student scores. Even small amounts of between-class variation caused large inflations in the Type I error rate of the t test. (Author/BW)
