Factorial ANOVA • With factorial designs we can break down1 the model variability into: • Main effects ▫ Mean differences among the levels of a particular factor • Interaction ▫ Differences among cell means not attributable to main effects ▫ When the effect of one factor on the ...

The main effects and binary, ternary and quaternary interaction effects were determined and the significance of effects was evaluated using normal order score and multifactor ANOVA. The organic chemicals retained after screening included, acetaldehyde, aniline, n-butanol, p-cresol, catechol, ...
Two-way ANOVA is a way of studying the effects of two factors separately, such as their main effects, and together, with their interaction effect. 8.3.1 One-factor-at-a-time design In one-factor-at-a-time design, one conducts the experiment with one factor at a time. Here, we hold ...

To determine if group differences were found, perform a two-way ANOVA to reveal any main or interaction effects. In this case, the effect on self-awareness depends on the level of self-esteem. Contrary to the hypothesized pattern, notice that participants with high self-awareness and low self...
Changing the main effect of A (a one-factor plot) More importantly, pay heed to the warning at the top of the plot of A (Temperature). It states “Warning! Factor involved in multiple interactions.” You should never try to interpret main effects plots of factors involved in interactions ...
