DA0-002 practice examsFinished
CompTIA Data+ V2
A vendor-neutral entry into analytics for people who will not start on a cloud platform: the measurement types that decide which analysis is valid, transactional against analytical systems and the star schema, ETL against ELT, the quality dimensions and what cleansing does to a distribution, then descriptive statistics and the four types of analysis, significance distinguished from importance, choosing a chart that answers the question, and the governance roles and ethics a result is judged against.
What you get
Papers are cut from the bank and weighted like the real exam, and no question appears in two of them. Every wrong answer comes back on later days until you have it right.
