Thesis Keith Gale 20139.10 Tests of normality of participants responsesFollowing reversal of negatively worded questions used in the psychological contextof the questionnaire to align measures, tests of normality are undertaken prior toconducting further statistical techniques. This is to assess the distribution of scoresfrom responses from section 3 of the questionnaire and determine if results align withnormal distribution (Gravetter and Wallnau, 2000, p52).Descriptive statistics concerning information on variables are explored for section 3of questionnaire responses (questions 18 to 39 inclusive). Although at a later stageonly questions which relate to sociological behaviours will be examined, the wholeresponse to section 3 is analysed. The analysis is dissected into four groups to detectif any bias between groups is present. Results are shown in Table 9.7.Table 9.7: Descriptive statistics of responses for section 3 of the questionnaireSection 3Q18 to Q39Organisational group Statistic Std.
