1. D. The chart displays the mean and standard deviations for the data set which is the best measure of central tendency and dispersion/spread respectively for interval/ratio measurement. 2. 97.12 3. The mean baseline depression score is 14.00 and the post test mean depression score for the experimental group is 13.36. This shows that the mean for depression in this group decreased. According to the statement that empowerment techniques have an important role in self management of ESRD
