A2 Research Methods Flashcards
What is level of measurement?
Level of measurement is the type of data collected, for our purposes.
What is a type 1 error?
it’s a false positive result, where a researcher believes the IV caused a change in the DV but they’re wrong.
What is a type 2 error?
it’s a false negative result. Where they believe no significant effect was observed but actually it happened
What are the different types of level of measurement?
Nominal - discrete categories.
Ordinal - categories in a meaningful order.
Interval - units can be subdivided into set categories.
Ratio - a continuous scale with divisible measurement points.
What is Coding?

What is Inter-observer reliability?
The extent to which there is agreement between two or more observers involved in observations of a behaviour.
What is Reliability?
The consistency of measurements.
What is the Test-retest reliability?
The same test or interview is given to the same participants on two occasions to see if the same results are obtained.
What is Concurrent Validity?
A means of establishing validity by comparing an existing test or questionnaire with the one you’re interested in.
What is Face validity?
The extent to which test items look like what the test claims to measure.
