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.
Researchers can combine several above methods for the data collection. For example, researchers can invite shoppers at malls, and send willing participants questionnaires by emails. With the introduction of computers to the survey process, survey mode now includes combinations of different approaches or mixed-mode designs.
Survey methodology is "the study of survey methods". [1] As a field of applied statistics concentrating on human-research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.

Data collection is a research component in all study fields, including physical and social sciences, humanities, [2] and business ...
Situation sampling involves the study of behavior in many different locations, and under different circumstances and conditions. [2] By sampling different situations, researchers reduce the chance that the results they obtain will be particular to a certain set of circumstances or conditions.
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.
Observational research is a method of data collection that has become associated with qualitative research. [1] Compared with quantitative research and experimental research, observational research tends to be less reliable but often more valid [citation needed]. The main advantage of observational research is flexibility.
A single survey is made of at least a sample (or full population in the case of a census), a method of data collection (e.g., a questionnaire) and individual questions or items that become data that can be analyzed statistically. A single survey may focus on different types of topics such as preferences (e.g., for a presidential candidate ...
