Exam IIBA-CBDA topic 1 question 45 discussion

See pg 50 in CBDA guide Data validity: Is the data truly representative of an underlying construct? For example, is Win ratio a good measure of monthly sales performance? In the context of the job satisfaction survey, asking different questions to different employees about their job satisfaction is analogous to the example given in the excerpt. It raises the concern of whether the data (responses to different questions) is truly representative of the underlying construct (overall job satisfaction). Therefore, the concern of the business analyst about the validity of the survey is supported by the emphasis on data validity in the excerpt. The excerpt highlights that validity ensures that the data accurately represents what it is supposed to measure, which is precisely the issue with asking different questions to measure job satisfaction.
