c) The participants
d) Motivation
e) Whether or not they are using a standing desk
How many levels are there for the independent variable in Scenario?
a) Two
b) One
c) Four
d) Three
What is the dependent variable for Scenario?
a) The participants

1) What is the confound for Scenario D (you may list more than one, but you must give at least one!).
2) How could the confound be fixed in Scenario D? Be sure to tell me what technique you are using (constancy, repeated measures, randomization, elimination, or balancing), as well as how you would apply that technique to this specific scenario, and how that would fix this confound.
