Data analysis plan Analysis Plan. Data Integrity Preliminary Analyses: First we will compare demographics and primary study measures at baseline between randomized treatment groups, using ANOVA for continuous variables (or Kruskal-Wallis if parametric assumptions are violated) and using χ2 tests for categorical variables. Subsequent analyses will adjust for significant baseline differences among the randomized groups. Additionally, the data will be examined for both missing cases and outlier scores on measures. Variable distributions will be checked for normality and if necessary, transformations will be performed to normalize the distributions.
