TABLE 2: DESCRIPTIVE STATISTICS FOR EACH FACTOR MEAN 4.66 4.87 4.47 5.97 4.57 4.95
VARIABLE
Working Environment (WE) Employment Conditions (EC) Resources (RE)
Education and Training (ET) Skills Shortage (SS)
Propensity to Leave (PL)
STANDARD DEVIATION 1.09 1.13 1.14 0.99 1.29 1.19
Table 2 summarised the scores for each of the six variables. For example, in the case of Education and Training (ET), the score obtained from 300 respondents shows a mean of 5.97 and standard deviation of 1.00. Overall, the variable scores are generally centrally distributed as all the scores are close to average (agree somewhat), except one variable (Resources), score which is average (neutral) with the mean value of 4.47. It also indicates that all the variables' scores lie within ± 1 standard deviation from the mean, indicating that respondents did not vary much in their responses around the mean score.
Exploratory factor analysis
Table 3 indicates the exploratory factor loadings of the various factors tested in this study. These six factors were subjected to an exploratory factor analysis. According to Vinayan, Jayashree and Marthandan (2012: 36) a cut-off point of 0.5 is recommended and in general the cut-off line of 3 items loading per factor were used as the threshold to ensure practical significance for further analysis and to confirm convergent validity as loadings greater than 0.4 is considered significant (Johari, Yahya & Omar, 2011: 140). Some of the items/variables have thus been omitted for further analysis.
