Week 8: Case Study (graded)
Post 1:
Case Study Q1: Several variables are presented that may be related to job satisfaction.
Which variables are stronger predictors of job satisfaction? Might other variables not
mentioned here be related to job satisfaction?
Research shows that teamwork is positively related to job satisfaction. For example, Kruse
(1986) investigated the relationship of teamwork and job satisfaction among county staff.
There are two variables that do not appear to be good predictors of job satisfaction.
1. Overall quality of work environment: t- test static value is -.252 and p value
associated with t test is also very high (0.805).
2. Total hour worked per week: t- test static value is -.22 and p value associated with t
test is also very high (0.829).

In regard to the Discussion Question: To what degree can someone depend on the results of
the regression analysis? Why?
The regression hypothesis is given by
The null hypothesis is
•H0: There is no statistically significant relationship between dependent variable and
independent variables .
The alternative hypothesis is
•Ha: There is a statistically significant relationship between dependent variable and
independent variables .
ANOVA table provides us model fit or predictive power (estimate) of independent variable on
dependent variable.
From the ANOVA table we can observe p value associated with F test is less than 0.05(
p=0.000). Hence we reject null hypothesis and conclude that there is a statistically significant
relationship between dependent variable and independent variables.
