12.5 RANDOMIZED BLOCK DESIGN
We have already discussed that in one-way ANOVA the total variation is divided into two
components: variations between the samples or columns, due to treatments and variation within
the samples, due to error. There is a possibility that some of the variation, which was attributed to
random error may not be due to random error, but may be due to some other measurable factors.
If this measurable factor is included in the MSE, it will result in an increase in the MSE. Any
increase in the MSE would result in a small F value (MSE being a denominator in the F-value
formula), which would ultimately lead to ...
