Experimental ch 7

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
