Question

You are conducting a combined analysis of trials from different locations using the lmerTest package in R. The ANOVA Table for tests of fixed effects shows that the denominator degrees of freedom is 7.80 rather than an integer value as expected. A likely explanation for this is:

a.There was no direct test for the treatments, so an approximate error and approximate degrees of freedom were determined.

b.An adjustment has been made for multiple comparison tests

c.The data were completely balanced (no missing plots), so we would not expect the degrees of freedom to be an integer value.
