How do you remove duplicates from a dataset in Power BI?

The method of removing duplicates from a dataset in Power BI using the Remove Duplicates option in Power Query is effective because Power Query is specifically designed for data transformation and preparation. In Power Query, users have access to various tools that allow them to manipulate and clean their data before it even enters the Power BI model.

When you choose the Remove Duplicates option, Power Query scans the selected columns in your dataset and eliminates any rows that contain identical values across those columns, ensuring that only unique entries are retained. This action is crucial when preparing data for reporting, as duplicates can skew analysis and lead to misleading conclusions.

The other choices, while related to data handling, do not provide a direct or effective means of removing duplicates. Manually editing the dataset could be tedious and prone to human error, and applying filters on report visuals only alters how data is displayed, rather than modifying the underlying dataset. The Data Clean-Up feature, although useful for various data preparation tasks, does not specifically target duplicate removal in the same way that the Remove Duplicates option does.
