In the previous post, we have discussed the Principles of Experimental Designs. There we discussed the concept of Experimental design in statistics and their applications.

Topic 6: Randomized Complete Block Designs (RCBD's) [ST&D sections 9.1 – 9.7 (except 9.6) and section 15.8] 6.1. Variability in the completely randomized design (CRD) In the CRD, it is assumed that all experimental units are uniform. This is not always true in practice, and it is necessary to develop methods to deal with such variability.

RANDOMIZED COMPLETE BLOCK DESIGN (RCBD) Description of the Design Probably the most used and useful of the experimental designs. Takes advantage of … Data from a randomized block design may be analyzed by a nonparametric rank-based method known as the Friedman test. The Friedman test for the equality of treatment locations in a randomized block design is implemented as follows: 1. Rank treatment responses within …
