CUMULATIVE SPSS WORKSHEET INSTRUCTIONS
OVERVIEW
This worksheet is designed to assess your ability to evaluate research designs, determine the most appropriate
research design, conduct statistical tests using SPSS software, and present research conslusions (including
appropriately formatted figures) using professional conventions. Such skills are fundamental to critically
consuming, evaluating and producing research.
INSTRUCTIONS
Be sure you have reviewed this module’s assigned readings and presentations before completing this
assignment. This assignment is worth 90 points. Each question is worth 5 content points except #12, which is
worth 6 pts. Nine (9) points are assigned to general formatting. This includes using ensuring the homework is
completed and submitted according to the instructions, SPSS output and images are legible and relevant, and
that basic college level writing skills (e.g., grammar, sentence structure) are used in the results write-ups.
Answers should be placed where indicated (e.g., “ANSWER”). Note: all questions must be attempted to be
eligible for full credit of “format” points.
 You will use the M7 Cumulative SPSS Data file (an SPSS data file) to conduct most of the tests in this
assessment. It is located in the folder associated with this assignment.
 Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will
be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001).
Remember to check your graphs! You often have to ADD the y – axis title.
 Submit the file as a WORD document (.doc or .docx). Make sure the filename of your submission includes
your full name, course and section.
o Example: SPSS7_JohnDoe_515B01
Background information on the M7 Cumulative SPSS Data
Download the M7 Cumulative SPSS Data file associated with this worksheet. It has coded data that you will
use to design, conduct, and interpret to demonstrate mastery of research methods and. It is updated regularly,
so make sure you download the current file linked this specific term. Here is a description for each variable:

PSYC 515 SPSS M7 2
Cumulative Scenario 1 (30 pts)
Using the dataset provided, determine two variables that would be appropriate to assess using a two-group
design to assess a “difference”. It can be between-subjects (BS) or within-subjects (WS) design. Use your
selections to answer the following questions.
1. Decide on the two variables. List them using the names exactly as named within the SPSS file. For
each, identify the variable type (independent or dependent). For the independent variable, indicate
whether it is BS or WS. For the dependent variable, indicate its scale of measurement (nominal,
ordinal, or scale).
ANSWER
2. State the null and research hypotheses based on the variables you selected, labeling one as the “null”
and one as “research”. Explain why you used a one- or two-tailed hypothesis, noting the grade on that
portion is solely based on the consistency of your justification with your choice of tail type.
ANSWER
3. Paste all relevant statistical output in the space provided below:
ANSWER
4. Use the degrees of freedom from your SPSS output or if necessary, hand-calculate them using the
formulas in your e-book. Using the Appendix in your e-book to find the critical value, and list it here
(do NOT round – include all decimal places). Also label and state your obtained value from your SPSS
output. Is the critical value SMALLER or LARGER than the obtained value from your SPSS output?
Does this mean you REJECT or FAIL TO REJECT the null hypothesis? Does this mean the results are
“significant” or “non-significant”?
ANSWER
5. Create an appropriate graph in SPSS and format it using professional conventions. Present it as Figure
1 in the space below. Make sure you include the figure label (Figure 1), and create a Figure Title – all
of this must be in proper format (including spacing and font style).
ANSWER
6. Present the results using APA format. This includes a full write-up to include a complete statistical
notation as shown in the weekly presentations. Make sure to describe what the conclusions mean in
general terms. You must include a call-out to Figure 1. Examples of APA results sections are also
available in the “Helpful Hints” document.
ANSWER
Cumulative Scenario 2 (31 pts)
Using the dataset provided, select one variable that is within subjects (can be two or three levels) and one
that is scale that will serve as your dependent variable. You cannot use a scenario from a previous answer
(you can re-use one of the variables, but not both). Use your selections to answer the following questions.
7. Decide on the two variables. List them using the names exactly as named within the SPSS file. State
the null and research hypotheses based on the variables you selected, labeling one as the “null” and one
as “research”.

9. Use the degrees of freedom from your SPSS output or if necessary, hand-calculate them using the
formulas in your e-book. Using the Appendix in your e-book to find the critical value, and list it here
(do NOT round – include all decimal places). Also label and state your obtained value from your SPSS
output. Is the critical value SMALLER or LARGER than the obtained value from your SPSS output?
Does this mean you REJECT or FAIL TO REJECT the null hypothesis? Does this mean the results are
“significant” or “non-significant”?
ANSWER
10. Create an appropriate graph in SPSS and format it using professional conventions. Present it as Figure
2 in the space below. Make sure you include the figure label (Figure 2), and create a Figure Title – all
of this must be in proper format (including spacing and font style).
ANSWER
11. Present the results using APA format. This includes a full write-up to include a complete statistical
notation as shown in the weekly presentations. Make sure to describe what the conclusions mean in
general terms. You must include a call-out to Figure 2. Examples of APA results sections are also
available in the “Helpful Hints” document.
ANSWER
12. Discuss one concern you could imagine regarding internal validity, and one concern regarding external
validity as they specifically relate to the scenario you created for this section. (HINT: You can look up
the definitions of “internal validity” and “external validity” in your ebook glossery as a reminder – but
then must apply those definitions to envision your own concerns related to them!) The points are solely
on whether the justifications are consistent with the definitions and are realistic given the general
nature of the scenario you selected (3 pts each = 6 pts total)
ANSWER
Cumulative Scenario 3 (30 pts)
Using the dataset provided, select two variables you would like to examine regarding a “relationship”. Use
your selections to answer the following questions.
13. Decide on the two variables. List them using the names exactly as named within the SPSS file. Indicate
the scale of measurement for each variable (nominal, ordinal, or scale). State the null and research
hypotheses based on the variables you selected, labeling one as the “null” and one as “research”.
Explain why you used a one- or two-tailed hypothesis, noting the grade on that portion is solely based
on your justification.

14. Use the degrees of freedom from your SPSS output or if necessary, hand-calculate them using the
formulas in your e-book. Using the Appendix in your e-book to find the critical value, and list it here
(do NOT round – include all decimal places). Also label and state your obtained value from your SPSS
output. Is the critical value SMALLER or LARGER than the obtained value from your SPSS output?

Does this mean you REJECT or FAIL TO REJECT the null hypothesis? Does this mean the results are
“significant” or “non-significant”?
ANSWER
15. Paste all relevant statistical output in the space provided below:
ANSWER
16. Create an appropriate graph in SPSS and format it using professional conventions. Present it as Figure
3 in the space below. Make sure you include the figure label (Figure 3), and create a Figure Title – all
of this must be in proper format (including spacing and font style).
ANSWER

notation as shown in the weekly presentations. Make sure to describe what the conclusions mean in
