Question

Problem Set 2: Chi Square Test of Independence (8 pts)

A public opinion poll surveyed a sample of 70 attendees of a local fair. Respondents were classified by religious affiliation (Christian or Not) and by voting preference (Republican, Democrat, or Independent). Results are shown in the table below. Is there a difference between those who identify as Christian and not in voting preference? Create an SPSS data file to conduct the appropriate statistical test.

	Rep	Dem	Ind	RT
Christian	12	20	7	39
Not Christian	9	18	4	31
CT	21	38	11	70

Calculate the effect size (show all work and don’t round until your final answer – then, use two decimal places) – even if the results were nonsigificant.

Answer 1

		Col 1	Col 2	Col 3	Total
Row 1		12	20	7	39
Row 2		9	18	4	31
Total		21	38	11	70
