Descriptive Statistics are as follows: Summary measures for selected variables | | | | Work | Pay | Promotion | | Count | 50.000 | 50.000 | 50.000 | | Mean | 79.800 | 54.460 | 58.480 | | Median | 82.000 | 55.500 | 58.500 | | Standard deviation | 8.288 | 14.747 | 15.999 | | Minimum | 63.000 | 25.000 | 16.000 | | Maximum | 95.000 | 90.000 | 92.000 | | Range | 32.000 | 65.000 | 76.000 | | Variance | 68.694 | 217.478 | 255.969 | | | | | | | | | | | Overall, the nurses show the highest level of satisfaction with their work (mean = 79.80 and median = 82). The data shows 40 of the 50 nurses rated work satisfaction in the 70 to 90 range. Six nurses rate work satisfaction 90 or better. Satisfaction with pay (mean = 54.46 and median = 55.50) was the lowest rated followed closely by promotion (mean = 58.48 and median = 58.50). Improvements in the areas of pay and promotion may be worth further consideration.
* What measure of job satisfaction appears to generate the greatest difference of opinion among the nurses? Explain.
Measures of dispersion show the following: Variable | Range | IQR | Standard Deviation | Work | 32 | 15 | 8.29 | Pay | 65 | 16 | 14.75 | Promotion | 76 | 17.5 | 16.00 | The largest dispersion is associated with promotion indicating that this variable has the largest differences among the nurses. Some nurses are apparently very satisfied with the promotion opportunities with 11 nurses rating promotion 90 or better. On
