The video introduces the blocking strategy with a focus on blocking in two-level factorial designs. Randomization, blocking and replication are also discussed as three basic principles of experimental design.
This video was recorded by Dr. Erik Vanhatalo, Quality technology and logistics, Luleå University of Technology (LTU), Sweden. The primary purpose of this video is to be learning material for undergraduate and graduate students following a course in design and analysis of experiments at LTU. The course book used in these courses are primarily: Montgomery, D.C. (2013). Design and Analysis of Experiments. Wiley.
