The statistical software package, SPSS, was used to determine Cronbach's alpha values for the three predetermined factors. To confirm the internal reliability of the six factors, Cronbach's alpha values were calculated (refer to Table 4).
TABLE 4: CRONBACH'S ALPHA FOR SECTION A OF THE QUESTIONNAIRE Factor
Working Environment (WE) Employment Conditions (EC) Resources (RE)
Education and Training (ET) Skills Shortage (SS)
Propensity to Leave (PL)
Cronbach’s Alpha 0.82 0.89 0.86 0.81 0.71 0.87
The reliability coefficients of Cronbach's alpha values for the various factors are all above 0.7. It can therefore be concluded that all factors are internally reliable.
