Descriptive research is used to describe behaviors and attributes that are observed and measured, rather than tested with an experiment.
Provide examples of descriptive research in psychology.
Explain when descriptive research is useful.
Descriptive studies do not test specific relationships between factors; however they provide information about behaviors and attributes with the goal of reaching a better understanding of the subject.
Descriptive research is a useful method of gathering information on new subjects in order to create hypotheses or of gathering information on rare phenomena.
This method of research has the advantage of studying individuals in their natural environment without the influence of the artificial aspects of an experiment. It can also be used to document rare events or conditions that could not be reproduced in a laboratory.
The most common type of descriptive research is the case study, which provides an in-depth analysis of a specific person, group, or phenomenon. While findings cannot be generalized to the overall population, they can provide important information for future research.
Research studies that do not test specific relationships between variables are called descriptive studies. These methods are used to describe general or specific behaviors and attributes that are observed and measured. In the early stages of research it might be difficult to form a hypothesis, especially when there is not any existing literature in the area. In these situations designing an experiment would be premature, as the question of interest is not yet clearly defined as a hypothesis. Often a researcher will begin with a non-experimental approach, such as a descriptive study, to gain more information about the topic, before designing an experiment or correlational study to address a hypothesis.
Descriptive research is distinct from correlational research, in which psychologists formally test whether a relationship exists between two or more variables. Experimental research goes a step further beyond descriptive and correlational research, and randomly assigns people to different conditions, using hypothesis testing to make inferences about how these conditions affect behavior. Correlational and experimental research both typically use hypothesis testing, whereas descriptive research does not.
Descriptive research can be used to gain a vast, but often inconclusive, amount of information. It has the advantage of studying individuals in their natural environment without the influence of the artificial aspects of an experiment. This approach can also be used to document rare events or conditions that could not be reproduced in a laboratory.
One important kind of descriptive research in psychology is the case study, which uses interviews, observation, or records to provide an in-depth analysis of a single person, group, or phenomenon. Although case studies cannot be generalized to the overall population (as in an experiment) nor provide predictive power (as in correlational research), they can provide extensive information for the development of new hypotheses for future testing, and provide information about a rare or otherwise hard to study event or condition.
