When performing a statistical analysis, one of the simplest graphical tools at our disposal is a main effects plot. This plot shows the average outcome for each value. Stat > anova > main effects plot.
A main effects plot is a plot of the mean response values at each level of a design parameter or process variable. As you develop your skills in examining graphs that plot means, you should be able to look at the graph and visually guesstimate if there is, or is not, a main effect or interaction. Complete the following steps to specify which columns of data to graph.
There is a main effect when different levels of a factor affect the response differently. I have trouble interpreting interaction plots when there is an. Help to interpret an interaction plot?
A “main effect” is the effect of one of your independent variables on the dependent variable, ignoring the effects of all other independent variables. Look at the line to. In design of experiment, it is referred to as a factor but in.
Use main effects plot to see how one or more categorical factors influence the continuous response. A main effects plot graphs the response mean for each factor level connected. For the model with the interaction term you can report what effect the two predictors actually have on the dependent variable.
A line connects the points for each variable. Main effects and interaction effect. Maineffectsplot(y,group) displays main effects plots for the group means of matrix y with groups defined by entries in group, which can be a cell array or a matrix.
Minitab creates the main effects plot by plotting the means for each value of a categorical variable. In this example, the main effects plot shows that metal type 2 is associated with the highest strength and that a sinter time of 150 is associated with the highest strength. There is also an interaction.
