Research validity can be divided into two groups: internal and external. However, the scale is not valid because it does not display the actual weight of the item. For example, if a weight measuring scale is wrong by 4kg (it deducts 4 kg of the actual weight), it can be specified as reliable, because the scale displays the same weight every time we measure a specific item. Reliability alone is not enough, measures need to be reliable, as well as, valid. In simple terms, validity refers to how well an instrument as measures what it is intended to measure. Research validity in surveys relates to the extent at which the survey measures right elements that need to be measured.
