What will be the error degree of freedom for testing 5 varieties of wheat in Latin Square Design?

Correct option is A

· In a Latin Square Design (LSD), the degree of freedom (df) for error is calculated as: (n−1)(n−2)
· Where n represents the number of treatments (in this case, 5 varieties of wheat).
· Substituting the value: (5−1)(5−2)=4×3=12
· Therefore, the error degree of freedom is 12.
Correct answer: (a) 12
