Examples of the types of responses are, physical characteristics, social or group roles, personality, interests, beliefs and current feelings or emotions. (Phoenix 2007, p47)
Benefits of this method are firstly that it is very quick, the results can be analysed rapidly and it can be scaled up easily to a study of any size The method also encourages disclosure of more than...
