Experimental ch 7
| 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 |
