Planning an Experiment in the Company of Measurement Error
Levin, Joel R.; Subkoviak, Michael J.
Applied Psychological Measurement, 1, 3, 331-8, Sum 77

However, in the real world of behavioral research, errors of measurement cannot be neglected. The determination of sample size is discussed, and an example illustrates blocking strategy. (Author/CTM)
