What is a blocking variable in statistics?
Blocking is a technique (procedure) that is used in biological / agricultural field experiments to arrange experimental units in groups or blocks that are similar to one another. It is an attemp to improve comparisons of treatments. Blocking will reduce the source of variability and increase precision (and may be accuracy) The theoritical basis of blocking is represented b the following mathematical results. Given X and Y are random variables VAR(X-Y)=VAR(X)+VAR (Y)-2 COV(X,Y) Phendukani Hlatshwayo (M.Sc Agronomy, Candidate from South Africa)

What is a quasi experimental design?
A quasi-experimental design is a design that resembles and experimental design but does not have the key ingredient of random assignment. They involve selecting groups that are used to test a variable but with no random pre-selection process.
