The Cultural Diversity Task Force sponsored six events last year (e.g. ,Awareness Luncheon)and six events with the same names this year.To see how well the attendance last year correlated with attendance this year,the chairperson ranked the number of people attending each event during each of the two years and calculated a correlation.The chairperson used the Spearman rank-order correlation coefficient to determine if attendance this year at these events was greater than last year (a positive correlation).The correlation would have to be bigger than _______ to be "significant."
A)0.886
B)0.829
C)0.645
D)0.643

Quizplus · Accepted Answer

The significance level or critical value for a Spearman rank-order correlation coefficient with 12 pairs of ranks (because there are 6 events for 2 years) at a 0.05 level of significance is 0.829. Therefore, any correlation coefficient greater than 0.829 would be considered significant.
