Problem Set 1: Chi Square Test of Goodness of Fit
Research Scenario: A forensic psychologist is running a jury study to examine factors that
influence jury decisions. He hires actors to conduct a mock trial with the characteristics of
actual criminal trials, with the exception that the “jury” is larger than 12 people in order to
have a larger sample. At the end of the mock trial, he polls the jury participants and asks them
what their decision would be regarding the defendant: vote to convict, vote to acquit, or
undecided. He records the frequencies of answers in the table below.
Using this table, enter the data into a new SPSS data file and run a Chi Square Test of
Goodness of Fit to test whether the proportions are equal across categories. Remember
to weight cases as shown in the presentation. Create a simple bar chart to show the
relationship between the variables. Follow the directions below the table to complete the
homework.
