Validity refers to the extent to which a measurement tool is measuring what it is supposed to measure. In this case, the extent to which the differences in observed scale scores reflect true differences among objects on the characteristics being measured.

Generalizability refers to the extent to which the findings of a study can be applied to other contexts or populations. None of the above is not a correct choice as one of the options is correct.
