b. External Validity

    Cards (27)

    • What does external validity refer to in research studies?
      Generalizability of results
    • A study on social media impact on teens may not generalize to older adults
    • What does ecological validity measure in research?
      Real-world applicability
    • Studies from the 1950s on gender roles may not apply today
    • Sampling diverse populations ensures high external validity.
    • What is population validity concerned with?
      Generalizing to other people
    • Researchers should consider historical context to ensure temporal validity.
    • Why might a study on social media impact on teens not generalize to older adults?
      Lack of population validity
    • Lab experiments on memory may not accurately reflect memory in everyday life
    • What type of external validity is affected when findings from the 1950s on gender roles are applied today?
      Temporal validity
    • Studies in real-world settings enhance ecological validity.
    • Give an example of a study lacking population validity.
      Study on teens generalizing to adults
    • Lab memory tests may not reflect everyday memory
    • Temporal validity ensures that study results remain relevant over time.
    • What is the primary goal of assessing external validity in research design?
      Generalizing research results
    • A study on teens may not apply to older adults due to lack of population validity.
    • What does ecological validity refer to in research design?
      Real-world applicability
    • 1950s gender role studies may not apply today due to temporal validity issues.
    • Steps to ensure high external validity
      1️⃣ Sample diverse populations
      2️⃣ Conduct studies in real-world settings
      3️⃣ Consider historical context
    • A study on social media impact on teens might not generalize to older adults due to lack of population validity.
    • Why might lab experiments on memory have low ecological validity?
      Artificial conditions
    • Temporal validity ensures research findings remain relevant over time.
    • To assess external validity, researchers consider whether results can be generalized to other populations, settings, and times.
    • Match the type of external validity with its implication for generalizability:
      Population Validity ↔️ Results may not apply to other groups
      Ecological Validity ↔️ Results may not reflect real-world behavior
      Temporal Validity ↔️ Results may not apply over time
    • What type of external validity is affected if a caffeine study's test conditions don't mirror everyday scenarios?
      Ecological validity
    • A homogeneous study group may limit generalizability due to population characteristics.
    • Historical context can influence temporal validity in research.
