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?
