What you'll learn

Before meaningful analysis can take place, data must be gathered, refined, and transformed into a reliable foundation for decision-making. In this course, CompTIA Data+ (DA0-002): Data Acquisition and Preparation, you’ll gain the skills to collect, integrate, and refine data for analysis. First, you’ll explore data acquisition methods, including data integration, sampling, and surveys. Next, you’ll learn how to query, filter, join, and optimize datasets for accuracy and efficiency. Finally, you’ll apply transformation and cleansing techniques such as scaling, standardization, imputation, and parsing to ensure data quality. When you’re finished with this course, you’ll have the practical skills and knowledge needed to prepare, clean, and optimize data for analysis, advancing your readiness for the CompTIA Data+ certification and success in data analyst roles.
