Methodological issues Flashcards
Validity
The idea of ensuring research measures what it aims to measure, the study is ACCURATE
Making sure it measures how the IV affects the DV
Validity can fall under what categories?
Internal
External
Internal validity
Whether the test itself accurately measures what it intends to
Internal validity has what types of validity under it?
Face validity
Concurrent validity
Criterion validity
Construct validity
Construct validity
Ensuring the study measures what the researcher says it’s measuring and not measuring an extraneous variables’ affect (environmental or participant variables)
Face validity
How accurately the research looks to be testing what it’s meant to test at face value
Criterion validity
How much one measure predicts the value of future performance/ behaviour in a different test
Concurrent validity
When a test/research gives the same results as another study/ measuring device which is measuring same behaviour or concept
External validity
Whether research can be generalised to different people or situations
External validity has what types of validity fall under it?
Population validity
Ecological validity
Ecological validity
Considers whether the experiment resembles real life so participants show naturalistic behaviour to how someone would act irl
Ensures we are measuring how real people act
Population validity
How accurately the test or study measures behaviour in the general population
Thus can be generalised to the rest of the population
The benefit of ensuring a study is ecologically valid?
So behaviour is naturalistic and can therefore be translated to real life
What is the benefit of ensuring a study is population validity?
Ensures we can measure how the rest of population may respond
What is the benefit of ensuring a study has construct validity?
So the research is an actual measure of what it set out to measure
