A case study is performed by taking one individual and studying him in depth over a period of time (e.g. Freud's Little Hans). As a means of gathering data, it has some points in its favour: It provides a large amount of rich data, which is qualitative, that is, information which has a lot of descriptive detail.

However, it has drawbacks: 1  It is not possible to generalise from a case study. 2  Data may be hard to quantify. 3  Case studies can take a long time (many years in some case)  There is a risk that the experimenter becomes too involved and loses objectivity.

In a case study, a researcher studies a subject in depth. The researcher collects data about the subject through interviews, direct observation, psychological testing, or examination of documents and records about the subject. Next: Page 3 of Research Methods.

Research Methods. Example: The more years of education a person receives, the higher his or her yearly income is. A negative correlation (–) means that when one variable increases, the other one decreases. Example: The more hours a high school student works during the week, the fewer A’s he or she gets in class.

Descriptive or Correlational Research Methods. Case studies, surveys, naturalistic observation, and laboratory observation are examples of descriptive or correlational research methods. Using these methods, researchers can describe different events, experiences, or behaviors and look for links between them. However, these methods do not enable researchers to determine causes of behavior.

Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: observational methods, case-study methods and survey methods. This article will briefly describe each of these methods, their advantages, and their drawbacks.

A +0.9 or a –0.9 indicates a very strong correlation; a +0.1 or a –0.1 indicates a very weak correlation. A correlation of 0 means that no relationship exists between two variables. Common correlational research methods include case studies, surveys, naturalistic observation, and laboratory observation.

Observational Studies. In an observational study, the experimenter obtains information by observing how people respond to certain situations. In this case it is important to distinguish between observations and inferences: you can observe someone talking but can only infer that someone is listening.

Descriptive/Correlational Research. Any scientific process begins with description, based on observation, of an event or events, from which theories may later be developed to explain the observations. In psychology, techniques used to describe behavior include case studies, surveys, naturalistic observation, interviews, and psychological tests. Case studies.

This is not an example of the work written by our professional essay writers. This essay will look at difference between to research methods; Case Study and Observation. Case study is the understanding of the complex issues or can extend experience or add strength to what is already known through previous research. It is an in-depth study of an individual, group, incident or community.
