Research methods - Validity Flashcards
What is validity?
Validity is when a test measures what it is intended to measure.
What are the four types of validity?
Face, concurrent, ecological and temporal
What is face validity?
This is when a participant looks at a test and can tell what it is supposed to measure.
What is an example of face validity?
Another example would be if a student were to sit a biology paper and see questions in French, the student would doubt the validity.
What is concurrent validity?
When a test will produce the same (or similar) results to a benchmark test.
What is an example of concurrent validity?
An example would be when students wrote mock exams. If a student were to sit similar style papers as their actual GCSE and get similar results, there would be a high concurrent validity.
What does concurrent validity make sure of?
Makes sure that similar tests are produced. This is crucial especially for IQ tests which are given out to thousands of people. People would want to know that their IQ was accurately measured even if different tests were given.
What is ecological validity?
How well a test reflects real life situations. An example would be a driver’s test. A learner driver shold be able to park, merge, and brake during their because these will all be real-life scenarios when driving.
What is temporal validity ?
Temporal validity is how well a test’s results stand over time For example, GCSEs should have temporal validity to make sure that over the years, colleges and universities know what A/A* students are capable of.
How can concurrent validity be ensured?
Comparing the test results to an established test.
How can temporal validity be ensures?
Predicting results on a future test from a past test. If the tests are similar then there is temporal validity
