IBM SPSS Step-by-Step Guide: t Tests
Note: This guide is an example of creating t test output in SPSS
with the grades.sav file. The variables shown in this guide do
not correspond with the actual variables assigned in Unit 8
Assignment 1. Carefully follow the Unit 8 Assignment 1
instructions for a list of assigned variables. Screen shots were
created with SPSS 21.0.u08a1: t Tests
Refer to the Unit 8 assignment instructions for a list of assigned
variables. The example variables “lowup” and “final” are shown
below.
Step 1. Open grades.sav in SPSS.
DAA Section 2: Assumptions of t Tests
To complete Section 2 of the DAA, you will generate SPSS
output for a histogram, descriptive statistics, and the Shapiro
Wilk test. (Levene Test output will appear in Section 4 of the
DAA). Refer to previous Step-by-Step guides for generating
histogram output and descriptives output for the assigned Unit 8
assignment variable.
Step 2. Generate SPSS output for the Shapiro Wilk test of
normality. Select Analyze ( Descriptive Statistics ( Explore…
The Explore window will appear. Move the assigned Unit 8
assignment 1 variable into the Dependent List area. The “final”
variable is used as an example below. Select the Plots button.
Select the “Normality plots with tests” option. Press Continue
and OK.
Copy and paste the Tests of Normality in to Section 2 of the
DAA and interpret it.
The Levene Test is generated as part of the SPSS t test output
reported in Section 4 (discussed next). You do not have to
provide the Levene Test output twice; just report and interpret it
in Section 2 and the actual output will appear in Section 4.
DAA Section 4: Reporting of t Tests
DAA Section 4 involves generating the t test output and
interpreting it. The examples variables of “lowup” (lower
division = 1; upper division = 2) and “final” are shown below.
Step 3. Generate SPSS output for the t test. Select Analyze (
Compare Means ( Independent-Samples T Test…
The Independent-Samples T Test window appears. Move the
assigned Unit 8 Assignment 1 dependent variable into the Test
Variables window. Move the assigned Unit 8 assignment
variable into the Group Variable window. Notice the (? ?). The
values of the independent variable are assigned in the next step.
Press the Define Groups… button. Assign the corresponding
values. Group 1 = 1. Group 2 = 2. Press Continue and OK.
The Independent Samples Test output appears. Copy and paste
this output into Section 4 of the DAA and interpret it as
assigned in the Unit 8 assignment instructions.

For the SPSS Data Analysis Report assignments in units 6, 8,
and 10, you will use the Data Analysis and Application (DAA
Template) with five sections described below. As shown in the
DAA Template, label all tables and graphs in a manner
consistent with APA Style and Formatting guidelines. Citations,
if needed, should be included in the text and references included
in a reference section at the end of the report. The organization
of the report should include the following five sections:
Section I: Data File Description (One Paragraph)
· Describe the context of the data set. Cite a previous
description if the same data set is used from a previous
assignment. To increase formal tone of the DAA, avoid first-
person perspective "I." For example, do not write, "I ran a
scatter plot shown in Figure 1." Instead, write, "Figure 1
shows&ellip;"
· Specify the variables used in this DAA and the scale of
measurement of each variable.
· Specify sample size (N).
Section II: Testing Assumptions (Multiple Paragraphs)
· Articulate the assumptions of the statistical test.
· Paste SPSS output that tests those assumptions and interpret
them. Properly embed SPSS output where appropriate. Do not
string all output together at the beginning of the section. In
other words, interpretations of figures and tables should be near
(i.e., immediately above or below) where the output appears.
Format figures and tables per APA formatting rules. Refer to
the examples in the DAA Template.
· Summarize whether or not the assumptions are met. If
assumptions are not met, discuss how to ameliorate violations
of the assumptions.
Section III: Research Question, Hypotheses, and Alpha Level
(one paragraph)
· Articulate a research question (or questions) relevant to the
statistical test.
· Articulate the null hypothesis and alternative hypothesis for
the research question(s).
· Specify the alpha level (.05 unless otherwise specified).
Section IV: Interpretation (Multiple Paragraphs)
· Paste SPSS output for an inferential statistic and report it.
Properly embed SPSS output where appropriate. Do not string
all output together at the beginning of the section. In other
words, interpretations of figures and tables should be near (i.e.,
immediately above or below) where the output appears. Format
figures and tables per APA formatting rules.
· Report the test statistics. Refer to your Warner text, "Results"
examples at the end of the appropriate chapter for guidance.
· Interpret statistical results against the null hypothesis.
Section V: Conclusion (Two Paragraphs)
· Provide a brief summary (i.e., one paragraph) of the DAA
conclusions.
· Analyze strengths and limitations of the statistical test.

The example variables “lowup” and “final” are shown below. Step 1. Open grades.sav in SPSS. DAA Section 2: Assumptions of t Tests To complete Section 2 of the DAA, you will generate SPSS output for a histogram, descriptive statistics, and the Shapiro Wilk test. (Levene Test output will appear in Section 4 of the DAA). Refer to previous Step-by-Step guides for generating histogram output and descriptives output for the assigned Unit 8 assignment variable. Step 2. Generate SPSS output for the Shapiro Wilk test of normality. Select Analyze ( Descriptive Statistics ( Explore… The Explore window will appear. Move the assigned Unit 8 assignment 1 variable into the Dependent List area. The “final” variable is used as an example below. Select the Plots button. Select the “Normality plots with tests” option. Press Continue and OK. Copy and paste the Tests of Normality in to Section 2 of the DAA and interpret it. The Levene Test is generated as part of the SPSS t test output reported in Section 4 (discussed next). You do not have to provide the Levene Test output twice; just report and interpret it in Section 2 and the actual output will appear in Section 4.

The organization of the report should include the following five sections: Section I: Data File Description (One Paragraph) · Describe the context of the data set. Cite a previous description if the same data set is used from a previous assignment. To increase formal tone of the DAA, avoid first- person perspective "I." For example, do not write, "I ran a scatter plot shown in Figure 1." Instead, write, "Figure 1 shows&ellip;" · Specify the variables used in this DAA and the scale of measurement of each variable. · Specify sample size (N). Section II: Testing Assumptions (Multiple Paragraphs) · Articulate the assumptions of the statistical test. · Paste SPSS output that tests those assumptions and interpret them. Properly embed SPSS output where appropriate. Do not string all output together at the beginning of the section. In other words, interpretations of figures and tables should be near (i.e., immediately above or below) where the output appears. Format figures and tables per APA formatting rules. Refer to the examples in the DAA Template. · Summarize whether or not the assumptions are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions. Section III: Research Question, Hypotheses, and Alpha Level (one paragraph) · Articulate a research question (or questions) relevant to the statistical test. · Articulate the null hypothesis and alternative hypothesis for the research question(s). · Specify the alpha level (.05 unless otherwise specified). Section IV: Interpretation (Multiple Paragraphs) · Paste SPSS output for an inferential statistic and report it. Properly embed SPSS output where appropriate. Do not string all output together at the beginning of the section. In other words, interpretations of figures and tables should be near (i.e.,
  • 15. immediately above or below) where the output appears. Format figures and tables per APA formatting rules. · Report the test statistics. Refer to your Warner text, "Results" examples at the end of the appropriate chapter for guidance. · Interpret statistical results against the null hypothesis. Section V: Conclusion (Two Paragraphs) · Provide a brief summary (i.e., one paragraph) of the DAA conclusions. · Analyze strengths and limitations of the statistical test. Running head: DATA ANALYSIS AND APPLICATION 1 Data Analysis and Application (DAA) Template Learner Name Data Analysis and Application (DAA) Template Use this file for all assignments that require the DAA Template.
