Describe and give examples of these three primary research methods:
a) observation
observational method (sometimes referred to as field observation) human behavior is closely observed. There are two main categories of the observational method — naturalistic observation and laboratory observation.
b) surveys
In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.
c) controlled experiments.
Case study research involves an in-depth study of an individual or group of indviduals. Case studies often lead to testable hypotheses and allow us to study rare phenomena. Case studies should not be used to determine cause and effect, and they have limited use for making accurate predictions.
