research methods

• validity - the degree to which a test measures what it is supposed to measure
• reliability - the extent to which if the research is repeated, it would give the same results
• representativeness - the extent to which a sample is similar to the target population
• generalisability - the extent to which the findings of a study can be applied to other situations
• Pilot studies - a small scale study to test the feasibility of a larger study. It makes sure that the data produced is the data that the researcher wants.
• respondant validation - process where a researcher provides the participants with an account of their findings, and ask for feedback. It eradicates bias.
