Randomiza tion if done properly can keep study groups as similar as possible at the outset so that the investigators can isolate and quantify the effect of the interventions they are studying No other study design gives us the power to balance unkno 59:176:135:291 46:78!59:14:003 59:1705:291 52:92m=:1037,x11:000,x210:00(thenswapxi's).2 PIVOTING,PA=LUFACTORIZATIONFactorizationSolutionofAx=b,with(part.)pivoting.PermutationMatrices:apermutati CS648. .
