Overview
Given the current economy, where employees are asked to do more with less, job stress is at an all time high. An organization wished to determine what factors in the work environment were causing the most job stress.
A sixitem survey was administered to sample 202 employees. The survey was measured on the following scale:
Scale 
Code 
Strongly Agree 
5 
Agree 
4 
Neutral 
3 
Dis Agree 
2 
Strongly Disagree 
1 
The higher the number, the more favorable.
Below is each question. Employees rated each one using the scale above.
Q1. 
I have the resources I need (e.g., tools, equipment, supplies, personnel) to do my job effectively. (RESOURCES) 
Q2. 
Policies and programs help me balance my work and personal commitments. (WORKLIFE) 
Q3. 
I am satisfied with my involvement in decisions that affect me. (INVOLVEMENT) 
Q4. 
I have the opportunities to learn and grow in my job.(LEARN) 
Q5. 
I am satisfied with my total compensation (pay, benefits). (REWARDS) 
Q6. 
The amount of stress I experience on the job is reasonable. (STRESS)

1. Below is computer output from SPSS, the package used in the text. The table below has descriptive statistics for each variable measured the 5point scale, with 5 being “Strongly Agree” and 1 being “Strongly Disagree” (Favorable = “SA or A”
1a. Which variable is has the most favorable rating? (1 pt)
b. Which variable has the most variation in the response? (1 pt)
c. Below is a frequency distribution of thestress variable.

What percentage of respondents “Strongly Agree/Agree” with their stress level being reasonable? (One number)(1 pt)
What percentage of respondents “Strongly Disagree/ Disagree” with their stress level being reasonable? (One number) (1 pt)
2. In addition to the survey items, respondents were asked to report their age as follows:
Generation Y (Born 19812000) 
1 


Generation X (Born 19651980) 
2 

Baby Boomers (19461964) 
3 

Veterans (Born 19221945) 
4 
Below is output from an ANOVA to test if there are differences in stress levels between age groups.
What was is the null hypothesis?
What is the alternative hypothesis?

3. The organization that surveyed the employees wanted to know what factors influenced STRESS so they could take action. To do that amultiple regression analysis was run that regressed the all the items against the STRESS measure to see which ones had the most impact on stress. Below are the findings:
