The questionnaire looked like this: Altogether, the participants (N=150) had to respond to 18 questions on an ordinal scale and in addition, age and. Because we can t models with or without an interaction term, the same data will show di erent pro le plots depending on which model we use. You can use this code, but to have multiple plots, you need the subplot which is used as follows: % Code used in my paper on design of composite riser. Create a bar-error-plot in which we compare the fuel efficiency (cty) across front-, rear-, and 4-wheel drives (measured in variable ‘drv’). Confidence intervals in within-subject designs: A simpler solution to Loftus and Masson’s method. By default the levels of x. Repeated measures plot (20 articles) displaying mean outcomes at baseline and several follow-up times by treatment group. The command takes the general form: where var1 and var2 are the names of the explanatory. Plot-Definition-Options. Click on OK. Put bluntly, such effects respond to the question whether the input variable X (predictor or independent variable IV) has an effect on the output variable (dependent variable DV) Y: “it depends”. For the x-axis, we need to create a sequence of values to span a reasonable range of Hours, but we need only three values of Effort for spotlight analysis. Visualizing 2-way interactions from this kind of design actually takes more coding effort, because you will not be plotting the raw data.
