Question

In a field experiment conducted under RBD, the number of replications and the treatments should be adjusted in such a way that the error degree of freedom (d.f.) becomes :
(A) $<$ 12
(B) At least 12
(C) 12 or more
(D) n-12

• A. (A), (B) and (D) only.
• B. (B) and (C) only.
• C. (C) and (D).
• D. (B), (C) and (D) only.

Hint:

If you have a small number of treatments, you must increase the number of replications ($r$) to ensure the error degrees of freedom, calculated as $(r-1)(t-1)$, is at least 12.

Answer 1

The Correct Option is B
