Cards in this deck (25)
- 1what is validity?~ accuracy ~
being on target with what you are aiming to do; whether an observed effect is a genuine one - 2what are the three main areas of validity?• control
• realism
• generalisabilty - 3what are the two types of validity?• internal
• external - 4what is internal validity?what goes on inside a study e.g.
• whether the IV produced the change in the DV
• whether the research tests what it intends to test
• whether it possesses mundane realism - 5what is mundane realism?how a study mirrors the real world; research environment
- 6what is external validity?the degree to which a research finding can be generalised; affected by internal validity. e.g.
• the place where research was conducted
• the people who are studied
• the historical period - 7what types of validity are applicable to internal validity?• construct validity
• content validity
• predictive validity - 8what types of validity are applicable to external validity?• ecological validity
• population validity
• temporal validity
• concurrent validity
• face validity - 9what is construct validity and how may you measure it?how closely performance links to previous theoretical concepts and existing literature
• ask an expert to check all items are related to background theory and literature - 10what is content validity and how may you measure it?at an individual item level, how closely the test/measurement is focused on the right topic
• check the face and construct validity - 11what is predictive validity and how may you measure it?how accurate research is at predicting other aspects of the focused behaviour or trait
• gather scores and then gather more information on a predictive behaviour. compare the two; strong correlation has predictive validity - 12what is ecological validity and how may you measure it?how much the research can be generalised to other settings
• repeat the research in different settings - 13what is population validity and how may you measure it?how much the findings can be generalised to all people
• apply results to a different culture and repeat the study - 14what is temporal validity and how may you measure it?how generalisable the study's results are over time
• repeat the study after considerable time and compare the results - 15what is concurrent validity and how may you measure it?is its measurements accurate in terms of how well it relates to pre-existing research
• compare measurement tools to well known existing tools results with the same participants - 16what is face validity and how may you measure it?how accurate it is in measuring what it intended to measure
• ask a colleague to review research from an intuitive perspective - 17what issues with the control aspect of validity may occur?• confounding variables
• extraneous variables - 18what issues with the realism aspect of validity may occur?• mundane realism
- 19what issues with the generalisation aspect of validity may occur?• ecological validity
• population validity
• temporal validity - 20what other threats to validity may occur?• demand characteristics
• researcher bias
• participant variables
• situational variables - 21what are demand characteristics?cues that may make participants aware of the aims of a study or helps them to work out what the researcher expects to find
• repeated measures; different times
• obvious what is being assessed - 22what is researcher bias?information from a researcher, other than the IV, that encourages certain behaviours in participants
• spending more time with certain participants
• using leading questions - 23what are participant variables?any characteristic of individual participants
a type of extraneous variable
e.g. age, intelligence, motivation, gender... - 24what are situational variables?features of a research situation that may influence participants behaviours
e.g. order effects - 25what are order effects?in a repeated measure design, an extraneous variable arising from the order of conditions
e.g. practice effect or fatigue
