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).
