Box Plot
Conclusion• Majority of the nurses rated pay and promotion
lower than work
• The nurses might not be satisfied with their pay and promotion as much as they are with the work
• The Healthcare should work on better pay structure and provide better opportunities to retain the nurses and avoid shortage of nurses in future.
• Improve the work quality in Private and VA.
