the consistency of the measure which must produce consistent results
1 of 14
inter-rater reliability
this is in observations where 2 observers consistently rate or observe the same behaviour and the 2 sets of ratings are correlated to ensure that observations are not subjective
2 of 14
internal reliabilty
consistency of results of a test across items within that test
3 of 14
external reliability
the extent to which a test score varires from one time to another, the consistency over time when repeated
4 of 14
Test retest
assesses external reliability give to the same participants on 2 occassions and correlate the results from both. strong positive correlation= good external reliabilty
5 of 14
Confounding variables
may affect the dependent variable and therefore reliability. All the varibles need to be controlled
6 of 14
Ecological validity
where the research is true to life e.g the situation or the behaviour e.g filed exp may be high
7 of 14
Face validity
on the surface does the task, question etc appear to measure what you aimed to measure
8 of 14
Internal validity
where the research does not have lots of extraneous variables and the effect of the independent variable on the dependent variable is truly being measured
9 of 14
External validity
where the research can be generalised to other settings/ environments e.g the popualation self reports may lack external validity as responses may be influenced by social desirability
10 of 14
Concurrent validity
where a test is validated against as existing measure e.g comparing a new method or test with an already well established one that claims to measure the same variable
11 of 14
Construct validity
where a test or study measures the actual behavour it sets out to measure, relates to an idea or construct e.g. is the intellgence test actually measuring intelligence
12 of 14
Criterion validity
can one measure predict or relate to another
13 of 14
Split half reliability
this assesses internal reliability where one and then the other half of questions are tested to ensure the same level of score is achieved on each half
