Thesis Keith Gale 2013Commentary upon Figure 9.4:Although the Shapiro-Wilk p value results indicated that this group (design) did nothave a normal distribution, use of a normal Quartile-Quartile plot shows adistribution of results that fit the normal distribution line reasonably well. Results areevenly spaced along the x-y axis with a slight reverse line profile. Apart from oneoutlier the distribution is accepted as suitable for further analysis.Figure 9.5: Normal Q-Q plot for Section 3 of the questionnaire –responses fromsupervision functionCommentary upon Figure 9.5:The Shapiro-Wilk p value results indicated that this group (supervision) did have anormal distribution. Normal Quartile-Quartile plot shows a distribution of results thatfollow a normal distribution line in overall context with results evenly spaced alongthe x-y axis to a slight reverse line variable curve profile. Values are toward thehigher end of the scale. Aside from three values the overall profile is balancedthroughout the line and this distribution is accepted as a normal distribution forfurther analysis.211
