Awesome video, thanks. Is there a video for external validity of pre-experimental, experimental, and quasi-experimental designs as well?

[@dr.b.sresearchclass9223]

Thank you. External validity is about the sampling process so you might find this video useful :) ua-cam.com/video/2epx1-BIaBI/v-deo.html
