In this study, participants were randomly assigned to one of two groups – to watch either a NEUTRAL or EMOTIONAL movie clip. After watching for an hour, participants were asked to rate work place satisfaction using an inventory that ranges from 0 – 10 (with higher indicating higher satisfaction). Assume data meets all assumptions for a parametric test. Using the information provided, create an SPSS data file and conduct the appropriate statistical test to determine whether there is a statistically significant difference in watching neutral or emotional movie clips before rating work place satisfaction. Answer the following questions based on your analyses.

In this study, participants were randomly assigned to one of two situations – “stress” or “no stress”. They were then put into their assigned fictitious situation and after an hour, were asked to provide an appetite score (Likert-rating). The following data are appetite scores (with higher indicating more of an appetite / i.e. the person is hungry) from 24 participants. Assume data meets all assumptions for a parametric test. Using the information provided, create an SPSS data file and conduct...
Problem Set 1: The One-way ANOVA Research Scenario: Depressed patients are randomly assigned to 1 of 3 therapists. At the end of 3 months, each patient completes a standardized test of depression (higher scores indicate higher level of depression). The patients’ scores are shown below. Analyze the data to determine how effective these 3 therapists are at treating depression (assume that before the treatment, all 3 groups of patients had the same average depression score). Using this table, enter the...
1. A research study randomly assigned participants into two groups. One group was given Vitamin E to take daily. The other group received only a placebo pill. The research study followed the participants for eight years. After the eight years, the proportion of each group that developed a particular type of cancer was compared. What is the primary reason that the study used random assignment? a. To ensure that the groups are similar in all respects except for the level...
SPSS Homework 1 Instructions: Review and One-Way ANOVAs (40 points) Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups. Problem Set 2: Pearson’s correlation (7 pts) Research Scenario: Is there a positive relationship between...
Part 2 – SPSS APPLICATION from this week’s assigned readings and presentations (28 pts) Problem Set 1: The independent-samples t test (7 pts) Research Scenario: A clinical psychologist is studying whether there is a difference between veterans diagnosed with PTSD and veterans without PTSD in reduction of anxiety after aerobic exercise. All veterans in this study agree to complete 30 minutes of aerobic exercise 5 days a week for 4 weeks and began with similar levels of reported anxiety. Scores...
Problem Set 2: Two-way mixed design ANOVA (8 pts) Research Scenario: A researcher is attempting to determine the effects of age and sleep deprivation on a reaction time task. Participants (5 “old”; 5 “young”) in an experiment are given a computerized search task. They search a computer screen of various characters and attempt to find a particular character on each trial. When they find the designated character, they press a button to stop a timer. Their reaction time (in ms)...

Part II: SPSS Application These questions require the use of SPSS. Remember you must submit all of your work within this word document. You will need to take a screen shot of your data view if necessary, or copy and paste your output into the spaces below. Remember to report the exact p value provided by SPSS output – simply reporting p<.05 or p>.05 is not acceptable (unless SPSS output states p=.000 – in that case you can report p<.001)....
