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 moduleâs 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., âANSWERâ). Note: all questions must be attempted to be

eligible for full credit of âformatâ points.

ï· 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.

ï· 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 (youâd report p<.001).

Remember to check your graphs! You often have to ADD the y â axis title.

ï· 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

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 âdifferenceâ. 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 ânullâ

and one as âresearchâ. 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 â 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

âsignificantâ or ânon-significantâ?

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 â 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 âHelpful Hintsâ 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 ânullâ and one

as âresearchâ.

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 â 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

âsignificantâ or ânon-significantâ?

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 â all

of this must be in proper format (including spacing and font style).

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 âHelpful Hintsâ 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 âinternal validityâ and âexternal validityâ in your ebook glossery as a reminder â 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 ârelationshipâ. 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 ânullâ and one as âresearchâ.

Explain why you used a one- or two-tailed hypothesis, noting the grade on that portion is solely based

on your justification.

(do NOT round â 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?
