According to R. A. Fisher, which of the following is not a principle of experimental design ?
Principle of Observation
R. A. Fisher, in his work on agricultural field trials and in The Design of Experiments (1935), laid down the basic principles on which a sound experimental design rests.
Replication means repeating the treatment on several experimental units so that experimental error can be estimated and precision increased.
Randomization means allotting treatments to units by chance, which protects the results from systematic bias.
Local control means grouping similar units into blocks so that variation from extraneous factors is controlled and the error is reduced.
Observation is a general method of collecting data used in all kinds of research; it is not one of Fisher's principles of experimental design.
Hence, Principle of Observation.
