From Problem 1,
a. at the 0.05 level of significance, is there evidence of a difference among the four group means?
b. at the 0.05 level of significance, is there evidence of an effect due to blocks?
Problem 1: Given a randomized block experiment with four groups and eight blocks, in the following ANOVA summary table, fill in all the missing results.
Source | Degrees of Freedom | Sum of Squares | Mean Square (Variance) | F |
Among groups | c - 1 = ? | SSA = ? | MSA = 80 | FSTAT = ? |
Among blocks | r - 1 = ? | SSBL = 540 | MSBL = ? | FSTAT = 5.0 |
Error | 1r – 12 | 1c - 12 = ? | SSE = ? | MSE = ? |
Total | rc - 1 = ? | SST = ? |
