A psychologist is interested looking at the effectiveness of a new computer program in helping students learn math. She decides to test this new program with a group of middle school students. At this particular school, the boys and girls tend to be disruptive when they are in the same classroom, so she decides to run them in separate groups in the Experiment. She creates a group of boys, each of them using the computer program four times per week. She creates a group of girls to serve as a comparison group and they do not get the computer program. This experimental design is flawed because gender is a Confounding variable and as a result the following has been lowered:

An educational psychologist wants to study the effectiveness of using the Internet as an instructional method for academic courses. She designs a study in which one group of students is assigned to take a course in a standard classroom with a live instructor. Another group of students is assigned to take the same course over the Internet. The psychologist then compares the course grades for students in each of the two groups. In this case, the instruction method (regular class vs. Internet class) would be considered the:

A clinical psychologist has developed a new form of psychotherapy to treat a particular personality disorder. In order to test its effectiveness, a group of people with the personality disorder is selected to receive the therapy for 8 weeks. A second group of people with the disorder is also created, but this group receives no therapy at all.

Dr. White wants to look at the impact of failure on self-esteem. He designs an experiment where half of the participants are led to believe that they have failed on an ambiguous task, while the other half of the participants are told that they have succeeded. Dr) White then has the people in his study complete a questionnaire measuring Self-esteem and he looks to see if there are any differences in self-esteem between the success and failure groups. In this example, self-esteem would be considered the:

A researcher who is interested in studying the effects of the amount of study time on exam anxiety selects a group of students to take part in her study. One group of students is allowed 10 hours of study time and a second group is allowed 20 hours of study time. Immediately before the exam, the researcher assesses each student's level of anxiety by measuring their blood pressure and heart rate. In this study, the independent variable is The ________, and the dependent variable is the _.
