Suppose that ten new smart phone models were evaluated by two consumer electronics magazines from 1 (best) to 10 (worst). Spearman's rho was calculated to be - 0.45. We can say that
A) there is a high level of agreement between the two magazine rankings.
B) the association between the two magazine rankings is strong and positive.
C) we use the Spearman's test as the Quantitative Variables Condition is satisfied.
D) the association between the two magazine rankings is moderate and negative.
E) as - 0.45 is roughly close to zero, there is very strong association between the two magazine ratings.

Question

Quizplus · Accepted Answer

Spearman's rho ranges between -1 to +1. A negative value indicates a negative association between the two variables. Therefore, option D is the correct answer, which indicates a moderate negative association between the two magazines' rankings. Option A and B are incorrect because Spearman's rho only measures the strength of association, not the level of agreement. Option C is incorrect because Spearman's test does not have a variable's condition. Option E is incorrect because -0.45 is not close to zero, and the association is negative, not positive.
