Forms of Validity in Research and Statistics

In this video, we'll learn about three commonly-discussed forms of validity: content validity, criterion validity, and construct validity. We'll also discuss the relationship between reliability and validity.

Pub Med is no longer a reliable source of research. Far too many ill funded "studies". Particularly in the arena of wireless radiation dangers. There are some telling the truth and some not. Wifi poses the greatest threat to human health that humanity has ever faced. I have lived this for 15 years, in addition to being in contact with thousands of people whose lives are now thoroughly ruined over it b/c they can't go anywhere in society anymore. Can't work, can't go back to school, can't get on a plane to visit family, etc.

Thank you so much! Finally a decent video. All the other videos are created by trolls who want to play with your sanity

You explain very well, great job, Prof. Thank you for this video. If I may ask, do you have some manual calculations of construct validity measures: convergent (composite reliability, average variance extracted)? Thank you.

[@nasserdana]

What about convergent validity ? Discriminate validity ? Where do they stand ?

[@aaronkoh4567]

Hi, could I ask, if I have an experiment that seeks to measure which burger is more popular, through a forced choice survey that only allows a selection of one burger,
Would that affect construct validity, considering that I have failed to account that someone may like both burgers equally much, or may dislike both burgers?
Would this pertain to construct validity? Or internal validity?

[@leonyannpruna1925]

Thank you sir!..can I have some of your examples to my report?..you explained it very well

[@vivekkumar-py6kp]

Good

[@suleimanidrisahmad9453]

So which of the Criterion and Content is external and which is internal validity?

[@olivianicastro5107]

what is the step if your CVI is low? Do you revise based on feedback and resend a CVI tool again to more experts?

[@kossonouprunelle7576]

For categorical variables (nominal and ordinal), is factor analysis or PCA better for construct validity?

[@jamunavinod9783]

Thank you so much for this wonderful video. It was such a relief to understand the facts so well explained. Blessed are your students
