Problem Set 2: Chi Square Test for Independence

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.

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.

Vote to convict	12
Vote to acquit	16
Undecided	7
