The Business Analyst to Data Analyst Proficiency benchmark will measure your ability to recall, recognize, and apply business analytics concepts and features of Tableau, Power BI, Python, and BigML. You will be evaluated on your ability to recognize and use business analytics techniques in Tableau, Power BI, Maria DB, Python, and Big ML for data visualizations using various charts, including Google charts. You will be evaluated on your ability to create dashboards; load data from a variety of files in Tableau; analyze tables; apply transformations, data validation, and cleaning; use pivot tables; use Python pandas for data analysis; and leverage Maria DB and BigML for machine learning models. A learner who scores high on this benchmark demonstrates that they have strong skills in business analytics and data analytics to build effective dashboards and share reports and insights with business users.
