Let's say that we want to run an experiment to test whether artificial sweeteners have the same effect on cognitive ability as real sugar. To do this, we make a bunch of very sweet milkshakes for our participants: Half of the milkshakes are sweetened with real sugar, and the other half of the milkshakes are sweetened with artificial sweetener. We bring in a bunch of participants and have them all drink their milkshakes at the same time, and then we give them all the same math test. For this experiment, match each of the following design choices to part of the scientific method that best describes them. operational definition of dependent variable independent variable operational definition of independent variable dependent variable A. performance on math test B. milkshake with artificial sweetener or real sugar C. type of sweetener (artificial sweetener or real sugar) 4. Cognitive ability

Check any/all that apply] Garrett is planning to do a case study for an upcoming research project. What should he be concerned about?
- He will need to recruit a large number of participants.
- He will need to be careful to avoid experimenter bias.
- He will not be able to establish causality.
- He will not need to be as concerned with how his findings generalize.
