Hi,
Can someone help me as to why the mean is negative? How does the negative come about? Someone said that this would essentially indicate that there are no significant group differences with respect to these variables based on the data analyzed. I fed this into SPSS but what is the mathematics behind it? I mean how is this mean calculated when SPSS does this? I thought it is the total scores of say 1-SD, 2-D, 3- N, 4-A, 5-SA and divide that with the number of factors that I have with e.g. Conf Level Factor. Shouldnt this be positive?
