A wide range of research methods are used in psychology. These methods vary by the sources from which information is obtained, how that information is sampled, and the types of instruments that are used in data collection. Methods also vary by whether they collect qualitative data, quantitative data or both.
Truly different methodology – When using multiple methods, one must consider how different the actual measures are. For instance, delivering two self-report measures are not truly different measures; whereas using an interview scale or a psychosomatic reading would be.
Methods can be categorized by the kind of data they produce: qualitative or quantitative—and both these are used for pure or applied research. Psychology tends to be eclectic, applying knowledge from other fields. Some of its methods are used within other areas of research, especially in the social and behavioural sciences.
Grounded theory combines traditions in positivist philosophy, general sociology, and, particularly, the symbolic interactionist branch of sociology.According to Ralph, Birks and Chapman, [9] grounded theory is "methodologically dynamic" [7] in the sense that, rather than being a complete methodology, grounded theory provides a means of constructing methods to better understand situations ...
Ebbinghaus also collected data on his ability to memorize at different times of the day and under different conditions. His work later influenced G.E. Müller who continued the tradition of lists of items to conduct memory experiments on human subjects and using behavioural data to develop models of memory. [3]

Experimental psychologists employ human participants and animal subjects to study a great many topics, including (among others) sensation, perception, memory, cognition, learning, motivation, emotion; developmental processes, social psychology, and the neural ...
Common factors theory, a theory guiding some research in clinical psychology and counseling psychology, proposes that different approaches and evidence-based practices in psychotherapy and counseling share common factors that account for much of the effectiveness of a psychological treatment. [1]
This method represents the most extreme form of intervention in observational methods, and researchers are able to exert more control over the study and its participants. [2] Conducting field experiments allows researchers to make causal inferences from their results, and therefore increases external validity.
