In addition, we calculated bias-corrected and accelerated confidence intervals which are derived from the same bootstrap distribution of correlations; however, the intervals are adjusted (i.e., accelerated) to account for skewness in the bootstrap distribution. For each correlation, we conducted ...

three cases of skewness but no leptokurtosis, three cases of leptokurtosis but no skewness and two cases involving both skewness and leptokurtosis. In each of these cases, there is a departure fromH0bbut no departure fromH0a, soμ =0 andσ =1. Each line gives a description of the particu...

As indicated by the skewness and kurtosis of our measure in the descriptive statistics, the distribution of our measure violates the normal distribution resulting in a strong “floor effect” and a moderate “ceiling effect”. Transforming the distribution did not allow us to obtain a normal distri...
