A measure is doing something that resembles what it should be doing
Essentially, it means that the survey appears to measure what it is supposed to measure, without any empirical evidence to back up that it does what it is supposed to do. This is not an acceptable form of validity evidence. There is no calculation for face validity, as it is purely subjective.
