Quizplus · Accepted Answer

All the other values given in the summary (test statistic, p value, and degrees of freedom) are directly calculated from the data and can be considered accurate. Effect size, however, is not directly calculated from the data and requires additional information or assumptions, so it is possible that the reported effect size is incorrect.
