You are filling in the ANOVA table values for an experiment using a randomized complete block design.In the experiment, there are 5 treatment groups, 16 blocks.The treatments F value (Fstat) turns out to be 6.253.In determining the p-value for this result, you should use df1 = 4 and df2 = 15.

In a randomized complete block design with 5 treatment groups and 16 blocks, the degrees of freedom for treatments (df1) would indeed be 4 (since df = number of groups - 1). However, the degrees of freedom for the error term (df2) would be calculated based on the number of blocks and the number of treatments, which is (16-1)*(5-1) = 60, not 15.
