You are helping your friend with their research project. So far, your friend knows that they are interested in how the learning environment, specifically attending school in-person vs. remotely, affects people's attention spans and overall class enjoyment, but they want a second categorical factor to include that may interact with their learning environment IV. Their learning environment IV is between-subjects. You do not have to look up any research to answer this question. Use your intuitive reasoning to pick a relevant factor. Each 1-2 sentences. (a) Provide a second factor that your friend can use. State the name of your factor, what the levels are, whether it is a true IV or quasi-IV, and the type of IV (between-subjects or within-subjects). (b) Based on the second factor you came up with, write the full factorial notation for this new design. (Hint: This includes the number of IVs, the IV names, the number and names of each level, the type of each IV, and the type of experiment) (c) What are you able to examine with this new design that has 2 IVs that you would not able to do if this design only had 1 IV? (Hint: What is/are the type(s) of effect(s) only possible with 2 IVs? Don't just name the type of effect - define it also)
