Earlier in the chapter, we introduced the chi-square test of independence with a study examining the relationship between personality and color preference. The following table shows the frequency distribution for a group of n = 200 students who were classified in terms of personality (introvert, extrovert) and in terms of color preference (red, yellow, green, or blue). Do the data indicate a significant relationship between the two variables? Test with α = .05.
