In this article we will discuss about:- 1. Meaning of Experimental Designs 2. Principles of Experimental Designs 3. Factors. Meaning of Experimental Designs: Experimental designs are various types of plot arrangements which are used to test a set of treatments to draw valid conclusions about a particular problem. Before dealing with experimental designs, it is necessary to define experiment, treatment [...]
The following points highlight the nine criteria used for comparison of various experimental designs. The criteria are: 1. Condition of Use 2. Layout 3. Replications 4. Randomization 5. Local Control 6. Statistical Analysis 7. Components of Variation Estimated 8. Accuracy of Results Obtained 9. Efficiency. Criteria # 1. Condition of Use: The use of experimental design depends mainly on the [...]
The following points highlight the top six types of experimental designs. The types are: 1. Completely Randomized Design 2. Randomized Block Design 3. Latin Square Design 4. Split Plot Design 5. Lattice Design 6. Augmented Designs. Experimental Design: Type # 1. Completely Randomized Design (CRD): The design which is used when the experimental material is limited and homogeneous is known [...]
