Experiments are especially appropriate for research projects involving all of the following EXCEPT:

His experiment consists of administering a brief survey to a group, having them watch a movie, then surveying them as they leave to determine if any change occurred. What kind of design is Kyo utilizing?

A fully representative sample is not as essential in experimental research, because we are measuring effects on the individual, not the individual themselves.

Explain how a natural experiment differs from a traditional one. What are the advantages and shortcomings of using them?

An experiment examines the effect of the:

Jimmy's experiment requires him to tell subjects that they will be working in pairs to solve a problem when in reality he does not care about problem-solving.

A friend of yours, a senior, took the Graduate Record Exam in September and scored in the 99th percentile. In February, your friend took the same exam over again.

Since you were in the control group you simply gave up and quit studying. This exemplifies:

Professor Rose was asked to design an experiment to test whether obese people would lose weight on a Pickup diet plan. Professor Rose was not a methodologist. Rose asked for your help. You immediately told Rose that the selected design would have to be sensitive to the issues of statistical regression, mortality, and demoralization. Rose said, "I don't understand." Explain these issues to Rose. Suggest and explain a design that would control for these problems.

Deception is often an important part of experimental research design. What are the ethical implications of using deception in your experiment? How do researchers decide whether to use deception?

It has been suggested that within a large enough experiment and with truly randomized assignment to experimental and control groups, a pretest is unnecessary.

Provide an example of a topic that would be well suited to an experimental study and an example of a topic that would not be well suited to an experimental study. What makes a study appropriate for experimental research?

Without randomly assigning subjects, a researcher administers the experimental stimulus to the experimental group and then measures the dependent variable in both the experimental and control groups. This design is known as the:
