D Question 22 4 pts Last question :) This is worth FOUR points so please submit something even if you're not sure what to do! You'd like to see if there's a relationship between people who attend office hours or Zoom discussions and a student's math grade. You first find LMC students who took math last semester. Then you ask them if they went to office hours or Zoom discussions and what grade they got in their math class. This is an observational study. How could you change things to make it an experiment? 1. Create a block experiment and upload your document. 2. Label or write down the explanatory variable 3.
