Reliability

• Reliability


  Results are consistent, replicating would result in similar results
• External Reliability


  Extent to which a measure is consistent when repeated
• Internal Reliability


  Extent to which different parts of a measure are consistent with itself
• Improving reliability:

  • Observation - pilot studies
  • Interviews - standardised
  • Questionnaires - closed Qs
  • Experiments - standardised
