Kinds Of Experimental Designs And Control
 
 
Experimental designs refer to the framework of structure of an experiment and as such there are several experimental designs. Generally, experimental designs are classified into two broad categories: informal experimental designs and formal experimental designs. Informal experimental designs are those designs that normally use a less sophisticated form of analysis based on differences in the magnitudes, whereas formal experimental designs offer relatively more control and use precise statistical procedures for analysis. Important experimental designs are discussed below:
 

Informal Experimental Designs:

 
 
1. Before and after without control design
 
2. After only with control design
 
3. Before and after with control design
 
 

Formal Experimental Designs:

 
1. Completely randomized design (generally called C.R design)
 
2. Randomized block design (generally called R.B design)
 
3. Latin square design (generally called L.S design)

4. Factorial designs.
