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).

Famous quotes containing the words key and/or numbers:
“Yes, I know.
Death sits with his key in my lock.
Not one day is taken for granted.
Even nursery rhymes have put me in hock.”
—Anne Sexton (1928–1974)
“The barriers of conventionality have been raised so high, and so strangely cemented by long existence, that the only hope of overthrowing them exists in the union of numbers linked together by common opinion and effort ... the united watchword of thousands would strike at the foundation of the false system and annihilate it.”
—Mme. Ellen Louise Demorest 1824–1898, U.S. women’s magazine editor and woman’s club movement pioneer. Demorest’s Illustrated Monthly and Mirror of Fashions, p. 203 (January 1870)
