The results and an excerpt from the results section of this fictional study follow. Observed (and Expected) Frequencies (NOTE: Expected frequencies are in parentheses.) Excerpt: "A chi-square test for independence was conducted to explore the relationship between whether a person had or had not sought psychological counseling and the person's profession (lawyer, car dealer, postal worker, high school teacher, or college professor.) A significant relationship was found, 2( N = 100) = 12.327, p < .05, such that...." 1)What percentage of college professors had sought counseling?

A social psychologist conducted a study to answer the question, "Does Smith's rehabilitation program decrease the rate of prisoners who re-offend?" The results and an excerpt from the results section of this fictional study follow: A chi-square test for independence was conducted to test whether Smith's rehabilitation program differed from the old system in the number of repeat offenders. Results indicated that a difference did exist, 2 (1, N = 68) = 8.74, p < .01. 5)Of prisoners in Smith's program, __________ % were repeat offenders. 6)Prisoners under the standard program represented __________ % of the repeat offenders. 7)According to this study, the program that appeared to be less effective in reducing the number of repeat offenders was __________. 8)The phi coefficient for this study was ______. 9)Explain, in your own words, what a chi square test is used for
