Method families Instructions: There are 5 methods, each with 3 strengths and 3 limitations. The aim is to collect a complete set for 1 method. Each player is dealt 6 random cards You take it in turns to request a specific card from another player – e.g. a strength of observation. If they have that card, they must give it to you. You can then ask another player for a different card. If they don’t have that card, then it is their turn to ask a player for a specific card. The game continues until somebody has a complete set of 3 strengths and 3 limitations for 1 of the methods. OBSERVATION The researcher observes behaviour in its true setting, so their evidence is likely valid. OBSERVATION It reveals meanings and motives behind behaviour. OBSERVATION The research often studies small groups so it may not be representative. OBSERVATION The research is based on verstehen, where behaviour is seen from the viewpoint of the actor. OBSERVATION The presence of the researcher may alter the behaviour of the group. OBSERVATION Objectivity may be undermined as the researcher becomes involved in the group or goes native. QUESTIONNAIRE QUESTIONNAIRE QUESTIONNAIRE Self-completion questionnaires avoid interviewer effects Large samples can be used. Different types of questions allow different types of data to be collected. QUESTIONNAIRE QUESTIONNAIRE QUESTIONNAIRE Generally there is a low response rate especially in postal questionnaires. Respondents may be forced into artificial categories. Respondents may not be honest. INTERVIEW Structured interviews can be replicated and produce quantitative data. INTERVIEW All types of interview are more time-consuming than questionnaires. INTERVIEW The qualitative data often provides rich insight into behaviour. INTERVIEW Unstructured interviews are difficult to replicate and they use small samples. INTERVIEW Unstructured interviews enable probing and help to establish rapport with the interviewee. INTERVIEW The validity of an interview rests on the quality of the question wording. DOCUMENT Unobtrusive, making reactive and investigator effects very unlikely. DOCUMENT Can be collected for time periods occurring in the past (e.g., historical data). DOCUMENT May be representative only of one perspective. DOCUMENT Can provide insight into what people think and what they do. DOCUMENT May be incomplete. DOCUMENT Access to some types of content is limited. OFFICIAL STATISTICS OFFICIAL STATISTICS OFFICIAL STATISTICS They can be quite cheap, easily accessible and up-todate source of data (which means the researcher doesn't have to spend time and money collecting information). The ability to assess trend changes over time is possible using historical statistics drawn from different periods (crime trends being an example here). Cross-cultural comparisons (crime rates in different countries, for example) are also possible - and are easy - using official statistics. OFFICIAL STATISTICS OFFICIAL STATISTICS OFFICIAL STATISTICS Statistics can be used to analyse only collective matters, and not individual events. Statistics are only valid as quantitative data. This cannot be used to study such events which cannot be expressed by numbers Reliability
