Communicare 24(1) - July 2005 Table 2 shows the t-Test results for research hypothesis 4, which predicted that subordinates from different population groups would differ in the levels of communication quality they reported. For the purposes of the statistical analysis, the coloured population group was excluded due to the fact there was only one respondent in this category. In this case the hypothesis was supported by the results – p=0.0255. Table 2:Subordinates from different population groups and the levels of communication quality reported A Pearson correlation coefficient analysis was conducted on research hypothesis 5. The hypothesis suggested that supervisors’ and subordinates’ assessments of LMX would be similar. The results of the analysis however indicated that there was a low correlation between the two (r=0.24, p=0.2262). The t-Test results associated with research hypothesis 6 stated that the perceptions of subordinates in diverse population group supervisor-subordinate pairs with regard to LMX would differ significantly from those of non-diverse supervisor-subordinate pairs. The statistical analysis however indicates that there is no significant difference between the perceptions of the diverse and non-diverse pairs – p=0.5929. Research hypothesis 7 stated that the perceptions of supervisors in diverse population group supervisor-subordinate pairs with regard to LMX would differ significantly from those of non-diverse supervisor-subordinate pairs. The statistical analysis (t-Test) however indicates that there is no significant difference between the perceptions of the different pairs – p=0.7900. Table 3 depicts the results of the statistical analysis conducted on research hypothesis 8, which stated there were significant gender differences in the supervisor communication quality. The t-Test results indicate that there are significant differences and this alternative hypothesis is therefore supported – p=0.0130.

Price & Bezuidenhout: Communication and leader-member exchange: a South African case study Table 4 contains the results of the statistical analysis for research hypothesis 9, which stated there are significant gender differences in supervisor LMX. The t-Test results confirm that there are significant differences and this alternative hypothesis is therefore also supported – p=0.0004. Table 4:Gender differences in supervisor LMX In view of the fact that the sample for this study was very small, a factor analysis could not be undertaken. The subordinate (N27) and supervisor (N22) questionnaires were however subjected to item analyses separate from each other and not in the dyadic relationship. This served to determine whether the respondents exhibited consistency
