validity & reliability Flashcards
define reliability
consistency of a test/measure
define validity
test measures what it intends to measure
Internal Validity
the extent to which the researcher measured what they intended to
- truth in study
external validity
the extent to which the findings in the study can be applied beyond the research setting e.g other situations, ppl, settings
Population Validity
concerns whether or not the findings can generalised to those outside of the study
Face Validity
examining the test to see if it looks like what it intended to
Concurrent Validity
involves comparing a new study with a well established study that claim to measure the same variable (s)
Ecological Validity
whether a test or method is representative of naturally occurring behaviour - can you generalise findings to other settings e.g everyday life ?
Predictive Validity
whether the test will predict future performance indicated by its results
which of these types of validity a type of internal validity
- face validity
- concurrent validity
types of validity that are eternal validity
- population
- predictive
- ecological
mundane realism
Extent to which the research settings resembles the
real-world setting
EXPERIMENTAL
REALISM
Degree to which the
experimental setting
and procedures are
real and involving to
the participants
Task : Define mundane realism. Can it affect validity of research
Mundane realism is the extent to which the research settings resembles the real-world setting. It effects
external validity of the research. It can be overcome with experimental realism; degree to which the
experimental setting and procedures are real and involving to the participant
External reliability
the extent to which the findings of a research study are consistent
