Assuming no bias, the total variation in a response variable is due to error (unexplained variation) plus differences due to treatments (known variation). If known variation is large compared to unexplained variation, which of the following conclusions is the best?
A
There is evidence for a difference in response due to treatments
B
The treatments are not comparable
C
There is significant evidence for a difference in response due to treatments
D
There is no evidence for a difference in response due to treatments
