Answer

E. Transforms and cleans data before analysis

Explanation

Power Query is a data transformation tool in Power BI that allows users to clean, reshape, and prepare data before analysis.

Power Query in Power BI is primarily used to transform and clean data before it is loaded into the data model for analysis. It serves as an ETL (Extract, Transform, Load) tool, enabling users to connect to multiple data sources, extract raw data, and perform a wide range of data preparation tasks such as filtering, sorting, merging, splitting columns, changing data types, removing duplicates, and reshaping datasets. Power Query provides a user-friendly, low-code interface that allows users to manage and automate these transformations without advanced programming skills. All transformation steps are recorded and can be reapplied automatically when refreshing data, ensuring consistency and reliability in reporting.

Power Query is dedicated to preparing, cleaning, and transforming data so that it is structured, accurate, and ready for analysis within Power BI, making it essential for effective data modeling and business intelligence.
