title: Manipulating the Factorial ANOVA
body: <p>How can I manipulate the data set for a 4x4 Factorial ANOVA in order to create the following situations:</p>
  <ol>
  <li>At least 1 significant main effect but non-significant interaction</li>
  <li>Non-significant main effects but significant interaction</li>
  </ol>
  <p>Is there a method or a principle in these kinds of manipulations? I understand the concepts, but struggle to learn how to deliberately create such situations.</p>
  <p>Thank you for your help.</p>
