find the rank correlation, coefficient for the following data
Answers
Answer:
Rank correlation coefficient = -0.5 .
Step-by-step explanation:
The rank correlation coefficient formula is given by;
r = where, D = difference between two ranks
i.e. D = Rank B - Rank A
n = number of observations.
Rank A Rank B D = Rank B - Rank A
1 4 4 - 1 = 3 9
2 5 5 - 2 = 3 9
3 6 6 - 3 = 3 9
4 7 7 - 4 = 3 9
5 8 8 - 5 = 3 9
6 2 2 - 6 = -4 16
7 3 3 - 7 = -4 16
8 1 1 - 8 = -7 49
∑ = 126
Rank correlation coefficient = = -0.5 .
