AP Psychology: Research Methods Used in the Study of Psychology - Chapter Summary
Because psychology is a scientific field, there are certain ways that psychologists perform experiments, gather data, and analyze their findings. Get ready for questions on the AP Psychology exam as you learn about ways to set up experiments, how research is conducted, and how to make sure your experiment is reliable and valid. After gathering data, psychologists have to analyze it, which you'll learn about in terms of statistics. Because psychology deals with humans, there can be some confusing ethical questions that arise, and you'll see how deception plays a part in many psychological experiments. After completing this chapter, you should be able to:
- Identify basic statistical data
- Describe different types of psychological research design and testing
- Compare basic and applied research
- Detail norm-referenced and criterion-referenced tests
- Discuss direct and indirect measurements
- Relate standardization information related to psychological tests
- Understand the use of random assignments and samples
