AB The value of R is 0.08438 and the two-tailed value of P is 0.81672. AC The value of R is 0.21296 and the two-tailed value of P is 0.5547 AD The value of R is -0.07548 and the two-tailed value of P is 0.83581. BC- The value of R is 0.12501 and the two-tailed value of P is 0.73077 BD The value of R is -0.4809 and the two-tailed value of P is 0.15941 CD-The value of R is -0.32396 and the two-tailed value of P is 0.36115 b. Which 2 judges are the most closely related? Which 2 judges are the least closely related?- c. Which judge was the kindest? -
Explanation / Answer
b.
The highest absolute value of R is for BD. (-0.4809). So, Judge B and Judge D are most closely related.
The lowest absolute value of R is for AD. (-0.4809). So, Judge A and Judge D are least closely related.
c.
Average rank assigned by Judge A = (5 + 9 + 3 + 8 + 6 + 7 + 4 + 8 + 4 + 6) /10 = 6
Average rank assigned by Judge B = (7 + 8 + 6 + 7 + 8 + 5 + 10 + 6 + 5 + 8) / 10 = 7
Average rank assigned by Judge C = (6 + 8 + 4 + 8 + 3 + 7 + 9 + 5 + 7 + 4) /10 = 6.1
Average rank assigned by Judge D = (9 + 8 + 9 + 8 + 9 + 10 + 6 + 7 + 8 + 7) /10 = 8.1
As, the highest average rank is assigned by Judge D, Judge D was the kindest.
