  1. Note. The mean values of groups on dependent variables are presented in the columns, with the standard deviations appearing in the parentheses immediately below the corresponding mean. Bonferroni adjustment to correct for an inflated Type 1 error rate (i.e., .05÷12 comparisons) yielded a significance level of p = .004. Therefore, interpretation of mean differences with associated significance levels above this are at a significantly increased risk for Type 1 error.
