Lesson 4: Blocking STAT 503
Table Of Content When to use a randomized block design? Analysis of Variance:Table of Contents Randomized Block Design: An Introduction Why is the randomized controlled double-blind experiment ideal? 2 Randomized Complete Block Designs Matched Pairs Design If you look at all possible combinations in each row, each treatment pair occurs only one time. Interpretation of the coefficients of the corresponding models, residualanalysis, etc. is done “as usual.” The only difference is that we do not test theblock factor for statistical significance, but for efficiency. I think most of the time it’s just a matter of convention, likely proper to each field. I think that in medical context, in a two factors anova one of the factors is almost always called "treatment" and the other "block". Identify potential factors that are not the primary focus of the study but could introduce variability. In the first example provided above, the sex of the patient would be a nuisance v
