  1. Questionnaires • What is an open question? Give an example. • What is a closed question? Give an example. • What is a rating scale? Give an example. • What is a pilot? Why is it useful? • What are the guidelines for designing a questionnaire? • What is a correlation? Give an example. • What are the advantages/ disadvantages of a questionnaire?

  2. Reliability • To say that a method is ‘reliable’ means that anybody else using this method (e.g same questionnaire, interview, observation) would produce the same finding e.g. If farmer measured the acreage of his farm one day using surveying equipment in good condition and the neighbour measures it a week later using equally good surveying equipment, they should get the same results.

  3. Validity • If a method is ‘valid’, it must measure what it set out to measure. e.g. We may want to investigate racism amongst the police force with an interview. Do the answers give us an idea of racist attitudes, or do they give us an idea of what police officers will say when they are asked about their attitudes to race?

  4. Representativeness • This is about how far the individual, group or situation being studied is typical for the rest of the population. If those being studied are typical, then we can claim that what is true of them is also true for the population.
