Research Scenario: A school psychologist has developed two voluntary programs for students in the first two years of high school: one that focuses on peer relationships, and another that focuses on study skills. She specifically wonders whether grade level is related to the type of program attended. She tallies the number of students from each grade who attended each type of program over one year. The results are listed in the table below.
Using this table, enter the data into a new SPSS data file and run a Chi Square Test for Independence to test whether grade level is independent of type of program attended. Remember to weight cases as shown in the presentation. Create a clustered bar chart to show the relationship between the variables.
- Write an APA-style Results section based on your analysis. Include your clustered bar chart as an APA-style figure as demonstrated in the APA writing presentation. (Results = 8 pts; Graph = 5 pts)

Problem Set 1: Chi Square Test of Goodness of Fit Research Scenario: A political psychologist is curious about the effects of a town hall meeting on people’s intentions to support a state proposition that would legalize gambling. He interviews people as they leave and asks them whether their opinion about the proposition has changed as a result of the meeting. He records these frequencies in the table below. Using this table, enter the data into a new SPSS data file...

Problem Set 1: Linear Regression Analysis Research Scenario: A community psychologist is interested in whether people’s self-reported degree of religious belief predicts their self-reported feelings of well-being. She administers two questionnaires to 17 individuals, one of which measures degree of religious beliefs (scores range from 1-20 with higher scores indicating higher degree of belief), and another which measures feelings of well-being (scores range from 1-25 with higher scores indicating stronger feelings of well-being). The psychologist compiles the information listed in...

Problem Set 2: Pearson Correlation Coefficient Analysis Research Scenario: A social worker involved in suicide prevention efforts wants to study the relationship between social isolation and possible suicide risk. She collects scores from a sample of 13 patients on two measures: one is a measure of social isolation on which higher scores indicate higher isolation (possible range of scores = 0- 20), and the other is the Suicide Risk Scale (SRS, Plutchik et al., 1989), on which higher scores indicate...

Problem Set 1: The independent-samples t test Research Scenario: A learning psychologist is interested in comparing the success of two different mnemonics (memorization methods) on performance in a memory task. He assigns students to two groups, one which learns and uses a language-based rhyming memory technique, and one which learns and uses a visual “method of loci” spatial memory technique. He then administers a memory task to each group of students. The students are scored based on the percentage of...
