Correlational Research Methods Correlational studies are one of the two major types of psychology research. Correlational studies are frequently used in psychology research to look for relationships between variables. While correlational studies can suggest that there is a relationship between two variables, finding a correlation does not prove that one variable causes a change in another variable. In other words, correlation does not equal causation. Learn more about the subtypes of correlational studies as well as methods of observation and scientific surveys. Why Correlational Studies Are Used Experimental Research Methods The simple experiment is one of the most basic methods of determining if there is a cause-and-effect relationship between two variables. A simple experiment utilizes a control group of participants who receive no treatment and an experimental group of participants who receive the treatment. Experimenters then compare the results of the two groups to determine if the treatment had an effect. Find more information on the parts of a simple experiment and how results are measured. Experimental Methods in Psychology Reliability Reliability is a vital component of a valid psychological test. What is reliability? How do we measure it? Simply put, reliability refers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly. Learn more about reliability in psychology tests. The Importance of Reliability in Psychological Tests Validity When determining the merits of a psychological test, validity is one of the most important factors to consider. What exactly is validity? One of the greatest concerns when creating a psychological test is whether or not it actually measures what we think it is measuring. For example, a test might be designed to measure a stable personality trait but instead, measure transitory emotions generated by situational or environmental conditions. A valid test ensures that the results are an accurate reflection of the dimension undergoing assessment. Why Validity Is Important to Psychological Tests Glossary of Terms Review some of the key terms that you should know and understand about psychology research methods. Spend some time studying these terms and definitions before your exam. 18 Psychology Research Terms You Need to Know Was this page helpful? Thanks for your feedback!
