Stat 2225 Handout Randomized Block Design Example Q15.35 on p. 496. Want to see if the 3 different courier companies (A, B and C) have the same delivery time for twelve different times of the day (blocks). Ignoring the blocking (i.e. ignoring the fact that they are matched), we are doing a one-way ANOVA: ANOVA Table for Time by Courier Analysis of Variance ----------------------------------------------------------------------------- Source Sum of Squares Df Mean Square F-Ratio P-Value ----------------------------------------------------------------------------- Between groups 204.222 2 102.111 2.05 0.1451 Within groups 1645.33 33 49.8586 ----------------------------------------------------------------------------- Total (Corr.) 1849.56 35 Step 1: H0: 1 µ = 2 = 3 vs. Ha: at least one pair of the courier services is different in terms of the time needed to deliver a package. Step 2: F statistic = 2.05. It has an F distribution with 2 and 33 degrees of freedom.
