Summary measures and statistics from study 2. Statistical significance between measures in the reflective questioning activity (RQA) and baseline conditions is indicated in the first column according to independent samples 1-tailed Welch t tests. Means are given with the SE within each condition. For each measure, we set our hypotheses as follows: the null hypothesis (H0) was that the mean for the RQA condition would be less than, or equal to, the mean for the baseline condition; by contrast, the alternative hypothesis (Ha) was that the mean for the RQA condition would be greater than the mean for the baseline condition.
