4 Model (cont’d) The effects are computed so that their sum is zero: The interactions are computed so that their row as well as column sums are zero: The errors in each experiment add up to zero:

8 Example 22.1: Computation of Effects An average workload on an average processor requires a code size of 10 3.94 (8710 instructions) Proc. W requires 10 0.23 (=1.69) less code than avg processor Processor X requires 10 0.02 (=1.05) less than an average processor … The ratio of code sizes of an average workload on processor W and X is 10 0.21 (= 1.62 ).
