The basis of my experiment are 4 neutral text snippets. For each text snippet, I create an uncertain and a certain version so that I have a total of 8 text snippets (2 versions for each text snippet, 1 certain and 1 uncertain version). The "version" of the text is the IV.
Now, the participants are randomly shown 4 text snippets at the same time (always 2 uncertain and 2 certain text snippets). The participants are asked to indicate if they perceive the text snippet as uncertain or not (DV).
On the one hand, I have a within-subject design because each participant sees uncertain and certain versions of text snippets. On the other hand, I have a between-subject design because a participant only sees either the certain or the uncertain version of a text snippet.
In my analysis, I will first examine the difference between the uncertain and certain versions in general (I sum up the results of the certain and the uncertain versions and compare the results). Then, I will examine the difference between the uncertain and certain versions of each text snippet.
My question is: What is the name of that setting? Is that setting a crossover-design?
