external validity Flashcards
what is external validity
the extent to which you can generalise the findings of a study to other situations, people, settings, and measures
how can we improve external validity
think about how you can make an experiment more realistic and representative of everyday life and if findings are relevant to outside people
what are specific ways to improve external validity
field experiments
what does ecological validity assess
the extent to which findings from a research study can be generalised to other settings/real life
what does temporal validity assess
the extent to which findings from a study can be generalised to historical times
what does population validity assess
the degree to which the study’s results can be generalised to a larger target group of interest(population)
how can we reduce social desirability bias
make it more internally valid - use filler questions to aim disguise
how can we reduce interviewer bias
make it more internally valid - structured interview rather than unstructured or interviewer blind to aim
how can we make a structured interview more valid
use an un/semi structured interview to build rapport and get more detailed answers
