You will complete this assignment using the DAA Template.
Read the SPSS Data Analysis Report Guidelines for a more complete understanding of
the DAA Template and how to format and organize your assignment.
Refer to the IBM SPSS Step-By-Step Guide: t Tests for additional information on using
SPSS for this assignment.
If necessary, review the Copy/Export Output Instructions to refresh your memory on how
to perform these tasks. As with your previous assignments, your submission should be in
narrative format with supporting statistical output (table and graphs) integrated into the
narrative in the appropriate places (not all at the end of the document).
You will analyze the following variables in the grades.sav data set:
gender
gpa
Step 1: Write Section 1 of the DAA.
•
•
•
Provide the context of the grades.sav data set.
Include a definition of the specified variables (predictor, outcome) and corresponding
scales of measurement.
Specify the sample size of the data set.
Step 2: Write Section 2 of the DAA.
•
•
•
•
•
•
Analyze the assumptions of the t test.
Paste the SPSS histogram output for gpa and discuss your visual interpretations.
Paste SPSS descriptives output showing skewness and kurtosis values for gpa and
interpret them.
Paste SPSS output for the Shapiro-Wilk test of gpa and interpret it.
Report the results of the Levene test and interpret it.
Summarize whether or not the assumptions of the t test are met.
Step 3: Write Section 3 of the DAA.
•
•
•
Specify a research question related to gender and gpa.
Articulate the null hypothesis and alternative hypothesis.
Specify the alpha level.
Step 4: Write Section 4 of the DAA.

Interpretation of effect size.
Means and standard deviations for each group.
Mean difference.
95% confidence interval of the difference of sample means.
Interpret the results against the null hypothesis.
Step 5: Write Section 5 of the DAA.

area.
Application of t Tests
For this discussion:
•
•
•
•
Identify a research question from your professional life or career specialization that can
be addressed by an independent samples t test.
Indicate why a t test would be the appropriate analysis for this research question.
Describe the variables and their scale of measurement.
Discuss the expected outcome (for example, “The Group 1 mean score will be
significantly greater than the Group 2 mean score because…”)
Response Guidelines
Provide a substantive contribution that advances the discussion in a meaningful
way by identifying strengths of the posting, challenging assumptions, and asking
clarifying questions. Your response is expected to reference the assigned
readings, as well as other theoretical, empirical, or professional literature to
support your views and writings. Reference your sources using standard APA
guidelines. Review the Participation Guidelines section of the Discussion
Participation Scoring Guide to gain an understanding of what is required in a
substantive response.

DATA ANALYSIS AND APPLICATION TEMPLATE
Data Analysis and Application (DAA) Template
Use this file for all assignments that require the DAA Template. Although the statistical
tests will change from week to week, the basic organization and structure of the DAA remains
the same. Update the title of the template. Remove this text and provide a brief introduction.
Section 1: Data File Description
1. Describe the context of the data set. You may cite your previous description if the same
data set is used from a previous assignment.
2. Specify the variables used in this DAA and the scale of measurement of each variable.
3. Specify sample size (N).
Section 2: Testing Assumptions
1. Articulate the assumptions of the statistical test.
2. Paste SPSS output that tests those assumptions and interpret them. Properly integrate
SPSS output where appropriate. Do not string all output together at the beginning of the
section.
3. Summarize whether or not the assumptions are met. If assumptions are not met, discuss
how to ameliorate violations of the assumptions.
Section 3: Research Question, Hypotheses, and Alpha Level
1. Articulate a research question relevant to the statistical test.
2. Articulate the null hypothesis and alternative hypothesis.
3. Specify the alpha level.
Section 4: Interpretation
1. Paste SPSS output for an inferential statistic. Properly integrate SPSS output where
appropriate. Do not string all output together at the beginning of the section.
2. Report the test statistics.

DATA ANALYSIS AND APPLICATION TEMPLATE
3. Interpret statistical results against the null hypothesis.
Section 5: Conclusion
1. State your conclusions.
2. Analyze strengths and limitations of the statistical test.
