Resource summary

VALIDITY

Annotations:

  • the degree to which something measures what it claims to.
1 Internal Validity

Annotations:

  • this is concerned with what goes on INSIDE the study.
1.1 Face validity

Annotations:

  • very basic form of validity in which you determine is a measure ''appears'' (on the face of it) to measure what is is supposed to measure.
1.2 Concurrent Validity

Annotations:

  • assesses validity by correlating scores on a test with another test known to be valid.
1.3 Predictive Validity

Annotations:

  • assess validity by predicting how well a test predicts future behaviour.
2 External Validity

Annotations:

  • this often affected by the internal validity- it is the degree to which a research finding can be generalised.
2.1 Ecological Validity

Annotations:

  • the place where the research was conducted. it may not be appropriate to generalise from the research setting to ther settings, most importantly to everyday life.
2.2 Population Validity

Annotations:

  • the people who are studied. if a research study involved just students or all men or only Americans etc. then it may not be appropriate to generalise the findings to all people.
2.3 Historical / Temporal Validity

Annotations:

  • the historical period. if a study was conducted in the 1950's it may not be appropriate to generalise the findings to people today because many other factors affect behaviour now.
