No parametric test | CJUS 745 – Quantitative Methods of Research | Liberty University

This
assignment has two parts and uses the 2018 Federal Employee Viewpoint Survey (Federal Employee Survey 2018. sav),
which you used in a previous module. Load the data set into SPSS.

RQ
6: Is there a significant difference in the agreement as to whether the federal
agency supervisor provides the employee with opportunities to demonstrate his
or her leadership skills (Q43) based on the sex of the employee (DSEX)?

·       
H₀6:
There is no statistically significant difference in the agreement as to whether
the federal agency supervisor provides the employee with opportunities to
demonstrate his or her leadership skills (Q43)
based on the sex of the employee (DSEX).

·       
H_a6:
There is a statistically significant difference in the agreement as to whether
the federal agency supervisor provides the employee with opportunities to
demonstrate his or her leadership skills (Q43)
based on the sex of the employee (DSEX).

1.     
Now,
perform a nonparametric Mann Whitney U
test with:

o  
sex (DSEX) as your independent variable groups
(male=1 and female=2) and;

o  
Q43 as your dependent variable.

2.     
Use
Cronk and provided resources to interpret the results of the Mann Whitney U
test.    

3.     
Click
on Analyze, Nonparametric Tests, Independent
Samples. 

4.     
Click
on use Compare Medians.  This is because the dependent variable Q43 is ordinal and not normally
distributed. 

5.     
Move
Q43 to test Fields box and MSEX to Groups box. 

6.     
Then,
Click on Run arrow. 

7.     
The
Hypothesis Summary appears.  Double click
on it and you get the graph and table as well on auxiliary view.

RQ
7: Is there a significant difference in the agreement as to whether the federal
agency supervisor provides the employee with opportunities to demonstrate his
or her leadership skills (Q43) based on the education level of the employee
(DEDUC)?

·       
H₀7:
There is no statistically significant difference in the agreement as to whether
the federal agency supervisor provides the employee with opportunities to demonstrate
his or her leadership skills (Q43) based
on the education level of the employee (DEDUC).

·       
H_a7:
There is a statistically significant difference in the agreement as to whether
the federal agency supervisor provides the employee with opportunities to
demonstrate his or her leadership skills (Q43)
based on the education level of the employee (DEDUC).

1.     
Now,
perform a nonparametric Kruskal Wallis H test
with:

o  
education level of the employee (DEDUC) as your independent variable groups (Less than Bachelor’s=1,
Bachelor’s=2, and Beyond Bachelor’s=3) and;

o  
Q43 as your dependent variable. 

2.     
Use
Cronk and provided resources to interpret the results of the Kruskal Wallis H test.  

3.     
Click
on Analyze, Nonparametric Tests, Independent
Samples. 

4.     
Click
on use Compare Medians.  This is because the dependent variable Q43 is ordinal and not normally
distributed. 

5.     
Move
Q43 to test Fields box and MSEX to Groups box. 

6.     
Select
Settings tab. 

7.     
In
the Settings tab, check Kruskal Wallis test. 

8.     
Then,
click on the Run arrow.

9.     
The
Hypothesis Summary appears.  Double click
on it and you get the graph and table as well on auxiliary view.
