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 Tukeys test
for any analyses requiring post hoc tests.

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
psychiatrists study. Specifically, the psychiatrist wants to measure whether a
new program helps decrease feelings of chronic pain in the short-term. He
measures childrens self-reports of pain levels before treatment on a standardized
scale with a range of 010, with 10 being the most severe. He then administers
the new program, and measures childrens pain levels after treatment. Does the
new treatment decrease self-reported
levels of chronic pain? (16 pts)

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. (16 pts)

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)

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 170,
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)

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:
