In a factorial design the “main effects” are
WebWhen the main effect of A is calculated, all other factors are ignored assuming that we don’t have anything else other than the interested factor, which is A, the temperature factor. Therefore, the main effect of the temperature factor can be calculated as A = (9+5)/2 - (2+0)/2 = 7-1 = 6. The calculation can be seen in figure 2. WebUsing the results from the full factorial design for main effects analysis, T was found to have the most significant effect on the average force (Favg), while α had the greatest effect on …

WebIn a factorial design, each level of one independent variable is combined with each level of the others to produce all possible combinations. Each combination, then, becomes a condition in the experiment. Imagine, for example, an experiment on the effect of cell phone use (yes vs. no) and time of day (day vs. night) on driving ability.

WebIn factorial designs, there are two kinds of results that are of interest: main effects and interaction effects (which are also called just “interactions”). A main effect is the statistical relationship between one independent variable and a dependent variable—averaging across the levels of the other independent variable.
