But how do researchers know that the scores actually represent the characteristic, especially when it is a construct like intelligence, self-esteem, depression, or working memory capacity? In other words, the zero value is a meaningful point on the measurement scale, and operations of multiplication and division are therefore also meaningful. Next is interval-level data, in which the requirements of ordinal level are met, and in addition, the intervals between each number are equal.
