Participants are also informed of any risk that might be encountered in the study (virtually none, in this case). Lastly, participants are given the opportunity to receive a summary of the final results of the study, once it has been completed. A feature that is new to the
note that this responsibility extends to everyone involved in the running of the study, from the primary researcher to the graduate students or undergraduates who might actually run the experimental sessions. We have already seen that the experimental psychologist must make an estimate of the amount of risk to participants, with greater amounts of risk creating a greater burden to justify the study. This problem of risk and potential harm is addressed in the standards relating to consent and
Box 4.3, which makes it clear that statistical analysis and graph making have an ethical dimension. Box 4.3 ETHICS—Lying with Statistics We’ve all been exposed to the deceptive use of statistical information. Although politicians might be the worst offenders, with writers of commercial ads perhaps a close second, statistics are abused frequently enough that many people tend to be skeptical about them, and you often hear people say things like ‘‘Statistics don’t really tell you anything

In the second part of this chapter, you will learn how the validity of a study can be affected by how well it is designed. When you finish this chapter, you should be able to: • Define a manipulated independent variable and identify examples that are situational, task, and instructional variables. • Distinguish between experimental and control groups. • Describe
