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

You
will take part in several data analysis assignments in which you will develop a
report using tables and figures from the IBM SPSS® output file of your
results. Using the resources and readings provided, you will interpret these
results and test the hypotheses and writeup these interpretations.

Instructions

·       
Copy
and paste all tables and figures into a Word document and format the results in
APA current edition. 

·       
Interpret
your results.

·       
Final
report should be formatted using APA current edition, and in a Word
document.

·       
4-5
double-spaced pages of content in length (not counting the title page or
references).

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.

1.      Address
the following research question using a nonparametric Mann Whitney U test:

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).

·       
Ha6:
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.

2.      Address
the following research question using a Kruskal
Wallis H test
:

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).

·       
Ha7:
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.
