RESEARCH STUDY 13.1
Mark conducts a study for his research methods class to determine if consuming caffeine causes people to perform better on cognitive tasks. In his study, he gives half of his participants a glass of water and half of his participants a glass of cola, and then has them attempt to solve 15 math problems. He finds that people who drink caffeine beforehand solve more math problems than those who drink water beforehand (p < 10.05).
-Refer to Research Study 13.1 above to answer the following question. Mark decides to conduct a conceptual replication.Which of the following could be in the study to make it this type of replication?
A) Measuring a different group of participants
B) Having participants drink a caffeinated energy drink rather than a caffeinated cola
C) Having participants complete a 20-item math test
D) Having participants complete a 10-item math test
E) All of the above

Conducting the same study but having participants drink a different caffeinated beverage (a caffeinated energy drink instead of a caffeinated cola) would be a conceptual replication because it tests the same hypothesis in a slightly different way. The other choices (measuring a different group of participants, changing the math problems, etc.) would not necessarily be a replication of the original study.
