Surveys

In surveys method, researchers collect information from a large group of people by using questionnaires, interviews or telephonically. There are different types of surveys. The most common and straightforward type is one shot survey in which people are surveyed in a set point in time. Another type is before and after survey, which people complete before and after event and experience and after wads.

Questionnaires

Questionnaire is a good method to collect and gather information from large group of people or from people who do not have time to participate in interviews or take part in experiments. They enable people to take their time, think about the questions and get back to it later on. Participants can give their views and opinion freely. However, unfortunately most of the participants do not give honest opinion while filling questionnaires. Questionnaire typically contain multiple-choice questions with a scale from highest to lowest. There are typically two types of questionnaires.

There are two types of interview methods. Formal interviews and informal interviews. Formals interviews are more structured and prepared beforehand and informal interview are not structured and you researcher ask questions according to the situation.

Case Studies

Case studies involve the detailed study of a particular case of a person or group. Various methods of data collection and analysis are used but this typically includes observations and interviews. Researchers may be interested in particular situation and may select one or more people to base their case study on. The results of the case studies can be obtained in the form of descriptive data

Studies using the Delphi method
