It is your turn to be a research scientist. You are very interested in student study habits. You will first look at the relationship between the total amounts of time spent studying and student grades. Then you will develop a hypothesis and test your idea.

Directions:

Work through the two research scenarios. You do not have to retype the questions; however, you must include the question # and answer in complete sentences.

Research Scenario 1

Your first research will be a correlational design. You are interested in whether or not there is a relationship between the amount of time a student studies and his or her grades.

State how and where you will collect your data (i.e. survey students).

Identify your variables. Are there any independent variables? Why, or why not?

Assume that your findings indicate that the more a student studies, the higher his or her grades are. Is this a positive or negative correlation?

Does this mean that more hours studying causes higher grades?

State at least 3 third variables that can cause higher grades.

Research Scenario 2

Now that you have discovered a relationship between the amount of time spent studying and student grades, you are interested in looking at why some students study more than others. Your next step will be an experimental research design.

State your hypothesis. (Why do you think one student will study more than another?)

Briefly describe your experiment (how will you test your idea). Be sure to include the following

Identify your control and experimental groups

Identify your independent and dependent variables

State how you will control for extraneous variables

What are your expected results?

Assuming that you have controlled for extraneous variables, can you infer causation? Why or why not?
