Research evaluation points
Term Definition/ Buzzwords
Generalisability ● Representative
● Target population
● The extent to which results can be generalised
beyond the sample to a wider population or situation
Reliability ● Results are replicable
● Control of extraneous variables
● Standardised procedure (same for every pp.)
Inter-rater ● Agreement between more than one
reliability researcher/observer on data gathered
● Check for consistency of results
● Less subjectivity = less bias
Application ● Useful: understand and change behaviour, develop
treatments etc
● Benefit to individuals/society
● Informs future research
Internal Validity ● Extent to which cause and effect conclusions can be
drawn from a study
● Control of conditions/ procedure so extraneous
variables do not affect the DV, only the IV does
● Cause and effect between the IV and DV can be
established
● Accurate results/conclusions
Population ● The extent to which the results represent other
Validity populations of people and the results can be
generalised (a type of external validity)
Demand ● Participants either become aware of the aim or try to
characteristics guess
● Change the behaviour being measured to fit the aim
or perceived aim
● Less accurate/valid results
