Experimental Design
Complete each section.
Create an experimental design.
Scenario:
You are very interested in finding out if eating apples can improve IQ scores.
Participants:
*20 randomly assigned students (Group A)
*20 randomly assigned students (Group B)
*20 randomly assigned students (Group C)
Supplies:
apples
mock apples

1. Describe, in detail, how you would conduct your experiment. Be sure to include enough details so that if someone were to read your details, they would be able to replicate your study exactly. Make sure you use all groups of participants and all supplies in your description.
2. Label and identify each part of the experiment:
a. Independent Variable
b. Dependent Variable
c. Control Group
d. Experimental Group
e. Was there a placebo in this experiment?
f. If so, what was it?
3. Let's say that your experimental results show that the Placebo Group increased their IQ score just as much as the Experimental Group. List two possible explanations for these results.
4. List two ways that you could improve on your experiment to determine if eating apples has any special effect (not just increased IQ) on people.
5. In the above experiment, describe what you would have to change to conduct it as a double-blind study.
