Question | Answer |
---|---|
research validity | degree to which conclusions from research match reality |
construct validity | extent to which the results support the theory behind the research |
internal validity | extent to which an experiment provides evidence of a cause-effect relationship between the iv/dv |
external validity | how well the findings generalize to other situations |
ecological validity | degree to which an experimental or laboratory setting mimics a real-world situation |
statistical validity | confidence that an observed cause-effect relationship between an iv &dv is true and not simply due to chance or accident |
sampling | large statistical power |
measurement | correct scale/precision |
analysis | inferential stats/hypothesis testing |
threats of internal validity | effects of repeat testing, regression towards the mean, selection bias, attribution, experimental bias |
threats of external validity | other subjects, other times, other settings |
threats of statististical validity | improper statistical analyses, low power |
