Completely Randomized Design - Three Key Numbers

Three Key Numbers

All completely randomized designs with one primary factor are defined by 3 numbers:

  • k = number of factors (= 1 for these designs)
  • L = number of levels
  • n = number of replications

and the total sample size (number of runs) is N = k × L × n. Balance dictates that the number of replications be the same at each level of the factor (this will maximize the sensitivity of subsequent statistical t- (or F-) tests).
