Analyzing randomized controlled interventions: Three notes for applied linguists
Languages of publication
The article discusses three common practices that obfuscate or invalidate the statystical analysis of randomized controlled interventions in applied linguistics. These are (a) checking whether randomization produced groupse that are balanced on a number of possible relevant covariates, (b) using repeated measures ANOVA to analyze pretest-postest designs, and (c) using traditional significance tests to analyze interventions in which whole groups were assigned to the conditions.
