The advantages and disadvantages of balanced incomplete block designs are clarified and their use is demonstrated with an empirical example. A procedure for reducing data of this type to analyzable form is proposed, and an analytical approach that is appropriate for the resulting data is illustrated. (Author/BW)

This study, involving five college students observing behavior of individuals with mental retardation, found that interobserver agreement was better in the presence of certain stimuli (such as when the subject's peers were present versus when they were not). Of 10 additional variables thought to potentially affect agreement scores, 1 (can't see,…

Rates of learning for five behavioral targets 3 months, 6 months, 9 months, and 12 months after the start of the diet were compared using a within-subjects…
