| measurement validity definition | Involves translating theory and concepts into observations and measures and focuses on how successful conceptualization and operationalization have been |
| 2 steps of measurement validity | conceptualization and operizationalism |
| what is conceptualization | in measurement validity, it is defining the construct (trait, concept) you want to measure |
| what is operationalization | in measurement validity, it is determining how to measure that construct |
| when is measurement validity threatened | there is systematic measurement error (ex. Your measurement is biased- occurs in one area but not another) or there is systematic bias- can be in the form of underreporting (not wanting to say something on a survey) |
| what are the 3 types of measurement validity | face validity, content validity, criterion validity |
| what is face validity | in measurement validity, it is the extent to which a measure makes intuitive sense |
| what is content validity | in measurement validity, it is the extent to which a measure captures - does it capture the range of what's out there |
| what is criterion validity | the extent to which a measure is empirically related to various criteria intended to demonstrate its validity (not common for social science) |
| reliability definition | consistency of measurement- produces consistent scores and nothing changes if you do it over and over - doesn't mean it measures what you want it to but it's consistent, answers are not scattered |
| what are the threats to reliability | random measurement error- people reporting different answers (like if you did or did not include yourself in the # of group members you have), answers are scattered |
| generalizability definition | the extent to which the findings of a study will hold true for a wider group/a wider context |
| what are the 2 types of generalizability | sample generalizability and cross-population generalizability |
| what is sample generalizability | Taking the results of a part of a larger whole |
| what is cross-population generalizability | Taking the results and seeing if they apply to a larger whole |
| what is a threat to generalizability | if the results may not hold true to a broader population/the population you're studying |
| causal validity definition | exists when a conclusion that the independent variable leads to variation in the dependent variable is correct |
| independent vs. dependent variable | thing causing the change vs. thing being changed |
| threat to causal validity | if some outside factor causes the change instead of the independent variable |
| what to look for in causal validity | association, time-order, no spuriousness, a causal mechanism, and context |
