Evaluation- Questionnaires

• Evaluation - strengths: questionnaires 


  +quick and easy: large amount of data in a short space of time

  +easy to analyse: especially closed questions and often easy to compare answers and spots trends in data.

  +fewer researcher effects: don't usually sit with PP so less chance to unconsciously influence.

  +standardised: can replicate questionnaire to asses answers for reliability.
• Evaluation - weaknesses: questionnaires 


  -low response rates: number of people returning questionnaire often quite low so means the ones that are returned will be from bias sample so not representative and can't be generalised to whole population.

  -difficult to analyse: time consuming and difficult to analyse as its qualitative data so subjective interpretation.

  -Social desirability bias: might not respond truthfully and very easy to lie on the test and answer to see them in a positive light.
