Refer to Exercise 15.44. Twelve pairs were entered in the ice-dancing competition. Once again, there were 9 judges, and contestants were assessed in seven subevents. The sums of squares between groups (pairs of contestants) and between blocks (judges) were found to be
In exercise
Source of Variation Sum of Squares
Between contestants ......... 364.50
Between judges ..........0.81
Interaction ............4.94
Error .............. 1,069.94
SSG = 60.10 and SSB = 1.65
while the interaction and error sums of squares were as follows:
SSI = 3.35 and SSE = 31.61
Analyze these results and verbally interpret the conclusions.
