DATA COLLECTION METHODS

Methods of data collection.

The term data means groups of information that represent the qualitative or quantitative attributes of a variable or set of variables. Data are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which information and knowledge are derived.

Data can be classified into primary and secondary data. In order to carry out research on a particular subject a researcher needs to collect data fro carrying out a research.

In contrived observation, the respondents’ behaviour is observed in an artificial environment, for example, a food tasting session.
Personal
In personal observation, a researcher observes actual behaviour as it occurs. The observer may or may not normally attempt to control or manipulate the phenomenon being observed. The observer merely records what takes place.
Mechanical
Mechanical devices (video, closed circuit television) record what is being observed. These devices may or may not require the respondent’s direct participation. They are used for continuously recording on-going behaviour.
Non-participant
The observer does not normally question or communicate with the people being observed. He or she does not participate.
Participant
In participant observation, the researcher becomes, or is, part of the group that is being investigated. Participant observation has its roots in ethnographic studies (study of man and races) where researchers would live in tribal villages, attempting to understand the customs and practices of that culture. It has a very extensive literature, particularly in sociology (development, nature and laws of human society) and anthropology (physiological and psychological study of man). Organizations can be viewed as ‘tribes’ with their own customs and practices.
