A Level Psychology - External Validity:

  • Concerns the extent to which research results can be generalised to other people and settings
  • If a study has low internal validity, it will lack external validity

Types of External Validity:

  1. Ecological validity
  2. Population validity

Ecological Validity:

  • Concerns the ability to generalise research beyond the particular setting in which it is demonstrated to other settings
  • In the case of an experiment the issue is whether the experimental represents the actual behaviour being investigated
