- Reliability is quality of repeatiblity - if we were to do this research again we should get the same results.
- Example of something being highly reliable is well designed questionnaires.
- Participant observations are seen as the least reliable and this is because these obsevations are carried out by lone sociologists.
- Quantative methods are more reliable than qualititive.

- Validity is what is the most true to what you are researching.
- Reliability and validity do not always go together - e.g. the questionnaires may be reliable but not valid as people can often lie.
- Observations studies are only valid when carried out well but they may not be reliable.

- Representativeness is a situation where a general group is used to represent a society.
- If the respondents in the study are not representative then it won't be possible to generalise the group or whole society.
