Question

Three judges A, B, C give the following ranks.Find which pair of judges has common
approach.
A : 1 6 5 10 3 2 4 9 7 8
B : 3 5 8 4. 7 10 2 1 6 9
C:6 4 9 8 1 2 3 10 5 7​

Answer 1

Answer:

A and C in common approach

Answer 2

Answer:

B : 3 5 8 4. 7 10 2 1 6 9

Step-by-step explanation:

Here we calcuate three rank correlation coefficient:

r12 beteen the ranks of judges I and II

r23 beteen the ranks of judges II and III

r13 beteen the ranks of judges I and III

r12=1-(6\sum∑D212)/(N(N2-1))=1-(6*200)/(10*99)=-0.212

r23=1-(6\sum∑D223)/(N(N2-1))=1-(6*214)/(10*99)=-0.297

r13=1-(6\sum∑D213)/(N(N2-1))=1-(6*60)/(10*99)=0.636

The Judges I and III have nearest approach to common tastes in beauty where as the Judges II and III disagree the most

b. yes, to find out the nearest approach to common tastes in beauty judges, we should calculate the sets of correlation between the pairs of judges
