Zip McMasterson is in a hurry to complete his research on the effects of stimulant consumption on driving behaviors

He decides that he could give 6 cups of coffee
to drivers from a local defensive driving class and observe the students' reactions
during their behind-the-wheel test. To insure that he is using good science, Zip
plans on using decaffeinated coffee with one group and regular coffee with the
other. Being that he personally knows the teacher of the class, he arrives the next
day with two large containers of coffee and began to administer it to the class.
What did Zip forget to do?
a. Provide participants with an informed consent form.
b. Receive certification from his universities' IRB.
c. He should have used a within-subjects design.
d. Both a & b.
e. All of the above.
