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

Thank you for the video

[@HarryJayCavite]

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.

[@ZA-ch5ur]

Well explained

[@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?

[@shubhankargupta4177]

[@suleimanidrisahmad9453]

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

[@kossonouprunelle7576]

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