Research Methods - Validity Flashcards
What is internal validity and how can this be improved.
Internal validity is the extent to which we can say that test is measuring what it is supposed to be measuring and is due to the iv , this can be improved by carefully looking at extraneous variables and making sure it is minimised.
What is population validity?
This how true the population of the sample is - how representative the sample is.
What are the two ways of assessing validity?
Concurrent Validity and Face validity.
What is face validity?
Face validity is a less rigorous way in testing to see weather its genuinely measuring what it is supposed to measure. - its simply seeing if the test appears at (face value) to measure what it claims
What is concurrent validity?
= Concurrent validity this is seeing how much something agrees , it involves assessing how closely the scores on a test match a different measurement from the same participant
