Cards (20)

  • What is the main focus of psychology in relation to measurement?
    Measuring behavior consistently
  • Why is reliability important in psychological investigations?
    It ensures consistent results across measurements
  • What is external reliability in psychological measures?
    Consistency of results when repeated by others
  • What is internal reliability in psychological measures?
    Consistency among different parts of a measure
  • How can internal reliability be assessed using a questionnaire?
    By splitting it into two parts and correlating results
  • What does a strong correlation indicate in the split-half method?
    It indicates internal reliability

    To assess external reliability of a measure
  • What happens if the same participants give different results in a test-retest?
    It indicates a lack of external reliability

  • How can researchers improve reliability in observational studies?
    By training observers and refining categories
  • Why should behavioral categories be operationalized?
    To ensure precise measurement of behaviors
  • How can interviews be structured to improve reliability?
    By carefully phrasing questions to avoid confusion
  • What type of questions can reduce confusion in questionnaires?
