I've just received some survey data and I found that the results are highly positively skewed. Most of the questions were answered on a five-point Likert scale, and the mean values of many questions are around 4.3, with standard deviations of 0.5 or 0.6.
Another problem is that in the questionnaire I included several multiple item scales that have been validated previously in the literature. However, some of these have very low Cronbach's alpha values (.4 or even .3) and I'm wondering how much of a problem this indicates.
Do these qualities indicate any intrinsic problems with the data set?
