Intro
The extent to which employees are stressed at work is an important managerial concern. After all, stressed employees may be less productive and less committed. The European Foundation for the Improvement of Living and Working Conditions gathers information on work-related stress in 5-year intervals and you are asked to analyse data from the two latest surveys, administered in 2010 and 2015. The sample consists of 3,991 Belgian employees. The Excel file labelled ‘BELGIUM' contains one sheet with the data and one sheet with variable definitions. Data cover indicators for characteristics of employees and their jobs, for company characteristics, and one indicator for the year in which the observation was collected.
Assignment
1. Provide a basic summary of the available data.
2. Is there evidence that the average level of job satisfaction has changed between 2010 and 2015?
3. Available research would lead us to expect that job satisfaction may be predicted by employee characteristics, characteristics of jobs, and company characteristics.
• Using the tool of regression analysis, does the data set imply support for such expectations?
• If so, then which employee, job, and company characteristics predict job satisfaction, and what is the nature of any such effects in terms of their sign and magnitude?
4. Job satisfaction may be lowest neither for very young nor very old employees, and so the association between age and job satisfaction may be U-shaped.
• Do the German data imply support for such an expectation?
Tools to use (not all is applicable, only what is useful)
• Bar chart
• Sample mean and the sample proportion
• Covariance and correlation
• Frequency distributions for ratio variables
• The normal and t- probability distributions
• Confidence intervals
• Simple linear regression
• Multiple linear regression
