Exercise 8-3b interpreting factorial designs
WebFeb 1, 2024 · Analysis of a factorial design: main effects The first step is to calculate the main effect of each variable. The effects are considered, by convention, to be the difference from the high level to the low level. So the interpretation of a main effect is by how much the outcome, y, is adjusted when changing the variable. WebFeb 1, 2024 · The y -variable represents the average amount of pollutant discharged (lb per day), while the three factors that were varied were C = the chemical compound added (choose either chemical P or chemical Q) T = the treatment temperature (72 °F or 100 °F) S = the stirring speed (200 rpm or 400 rpm) y = the amount of pollutant discharged (lb per …
