You Are Interested in Studying How Airline Pilots React in Emergency

Multiple Choice

You are interested in studying how airline pilots react in emergency situations. To preserve external validity, you want to use real airline captains. In this case, a within-subjects design would be most desirable because:

A) you do not have to worry about carryover effects with a highly trained subject sample.
B) subject variables probably do not contribute much to the value of the dependent variable.
C) highly trained airline pilots probably don't have the time to participate in a between-subjects design.
D) you will probably be faced with a limited supply of participants.
