Problem 5 of 7 Consider the standard definitions of sum of squared deviations in the two types of one factor ANOVA discussed in this unit. Prove the following. 1. SST = SSA +SSE (completely randomized ANOVA) 2. SST SSA +SSB SSE (randomized complete block ANOVA) 3. Prove the two alternative formulas for calculating the SSA,SSE,SST in the completely randomized ANOVA. Provide a justification of why someone may prefer to use these formulas against the others that calculate the sum of...

In a TWO-factor Analysis of Variance, total variance is partitioned into which of the following? (Look carefully at all the subscripted notations.) SStotal = SSa + SSb + SSwithin SStotal = SSa + SSb + SSab SStotal = SSab + SSwithin SStotal = SSbetw + SSab SStotal = SSa + SSb + SSab + SSwithin In a two-factor ANOVA, an interaction occurs whenever the effect of one factor: is found to be significant. is weaker than the effect of another...
