Unit of Analysis in Field Experiments: Some Design Considerations for Educational Researchers.
Mcmillan, James H.
Three experimental design issues are examined in relation to the appropriate unit of analysis. Independent replication of the treatments for each subject, independence of observations when gathering dependent variable data, and randomization of groups of subjects are factors that can affect the statistical model and interpretation of results. Examples from two recently published studies are provided, and implications for validity are discussed. (Contains 13 references.) (Author/SLD)
