SPSS Cumulative Assessment Instructions_x000d_
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._x000d_
_x000d_
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. _x000d_
_x000d_
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._x000d_

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)_x000d_

2. A health psychologist in a northern climate wants to evaluate the claim that UV lamps help lower depressive symptoms in middle-aged women. She recruits volunteers who meet the criteria for clinical depression and assigns them to two groups: one group receives a standard treatment for depression and undergoes a half hour of UV lamp therapy each day; the other group receives the same standard treatment for depression but without UV lamp therapy. At the end of two months, she administers a depression inventory where lower scores indicate fewer depressive symptoms (lower levels of depression). Assume all other variables are controlled for in the study. Evaluate the claim that depression treatment plus the UV lamp results in lower depression scores than depression treatment alone.

3. As part of a new prevention program, a clinical psychologist wants to see whether feelings of alienation differ as a function of immigration status in a local high school. She divides volunteer students into three categories: first-generation immigrants, second-generation immigrants, and non-immigrants. She then administers an instrument assessing feelings of alienation, where higher scores indicate stronger feelings of alienation from peers, adults, and society in general. Is there a difference in alienation scores among these three groups? (16 pts)_x000d_

4. In response to media reports of violence on college campuses, a psychologist who works at a local community college decides to study students’ perceptions of campus safety. He hopes to use these results to help develop an on-campus violence prevention program. The administration has asked him additionally to look at whether perceptions of safety differ depending on students’ year in school and gender. The psychologist administers a questionnaire with possible scores ranging from 1-70, with higher scores indicating higher perceptions of safety on campus, and lower scores indicating perceptions that the campus is less safe. Based on the data collected below, do year in school and/or gender have an effect on perceptions of campus safety? (16 pts)_x000d_

5. A cross-cultural psychologist living in an overseas, non-Western rural area has a background studying culture bias in traditional psychological testing procedures. She contends that members of a rural community who normally score lower than average on traditional Western-style IQ tests will score better than the general population on a new test that emphasizes practical and social intelligence. Scores on the test can range from 1–100. She recruits 18 volunteers and administers the new test. Their scores are as follows:_x000d_
