Where the p value (Sig.) is more than alpha = 0.05, results can beconsidered normal. Two results (supervision and other) can be considered of normaldistribution and results are explored further using graphical normal Q-Q plots.Figure 9.4: Normal Q-Q plot for Section 3 of the questionnaire –responses fromdesign function210
