An advertising research analyst wanted to test whether there is any relationship between a magazine advertisement's color intensity using a new digital photography technique introduced in 2007 and the ad's appeal. Ten ads of varying degrees of color intensity, but identical in other ways, were shown to randomly selected groups of respondents. The respondents rated each ad for its general appeal. The respondents were segmented in such a way that each group viewed a different ad, and every group's responses were aggregated. The results were ranked as follows.
Color intensity: 8 7 2 1 3 4 10 6 5 9
Appeal score: 1 3 4 2 5 8 7 6 9 10
Is there a rank correlation between color intensity and appeal?
