Assertion (A): Randomised trials are necessary to evaluate seeding.
Reason (R): The natural variability of rainfall greatly exceeds any plausible seeding effect.

  • A.Both A and R are true, but R is not the correct explanation of A
  • B.A is true but R is false
  • C.A is false but R is true
  • D.Both A and R are true, and R is the correct explanation of A

Answer: D

Both are true and the reason gives the statistical problem, and single case comparisons are worthless in consequence. Even randomised trials often require many seasons to reach a useful conclusion. Sample size is the binding constraint on such work.
