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 six-item survey was administered to sample 202 employees.  The survey was measured on the following scale:

The higher the number, the more favorable.

Below is each question.  Employees rated each one using the scale above.

1.  Below is computer output from SPSS, the package used in the text.  The table below has descriptive statistics for each variable measured the 5-point 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.  

                                                                                STRESS

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:

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?

Below are summary statistics for

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:
