SPSS CUMULATIVE ASSESSMENT INSTRUCTIONS
The following research questions can be answered using 1 of the 5 tests you have learned so far:
single-sample t-test, paired-samples t-test, independent-samples t-test, one-way ANOVA, or
two-way ANOVA. Use the information in the tables to construct your SPSS data file, just as you
have been doing in Part 2 of each homework assignment. There is only 1 correct choice of
analysis for each question, and note that some tests are 1-tailed and some are 2-tailed. The
assessment is open-book/open-notes.
For each problem involving a test of significance, your answer must include: A) SPSS output; B)
an appropriate graph from SPSS; C) a Results section in current APA style including a statistical
statement (i.e., t(19) = 1.79, p = .049); a sentence summarizing the results “in English” (i.e.,
“There was a significant difference between the two groups on the variable…” or “There was no
significant difference…”); and a decision about the null hypothesis.
For ANOVA problems: Report statistical findings and make statements for all main effects and
interaction effects. Use Tukey’s test for any analyses requiring post hoc tests. Do not create a
boxplot--use the graph we typically use in the course for this type of test.
Submit this assignment by 11:59 p.m. (ET) on Monday of Module/Week 5.
1. Children who experience chronic pain as a result of medical procedures are the focus of a
psychiatrist’s study. Specifically, the psychiatrist wants to measure whether a new program
helps decrease feelings of chronic pain in the short-term. He measures children’s self-reports
of pain levels before treatment on a standardized scale with a range of 0–10, with 10 being
the most severe. He then administers the new program, and measures children’s pain levels
after treatment. Does the new treatment decrease self-reported levels of chronic pain? (16
pts)
