2. Ensure data is clean and reliable: Metadata can include details about the data's source, quality, and accuracy. By examining the metadata, analysts can assess the reliability of the data and identify any potential issues or errors.

3. Choose which analyses to run: Metadata can provide insights into the variables and attributes present in the dataset. This information helps analysts determine which analyses are appropriate and relevant for their research or objectives.

4. Understand the contents of a database: Metadata provides a description of the data, including its structure, relationships, and meaning. By reviewing the metadata, analysts can gain a better understanding of the database's contents and how the data is organized.

Therefore, metadata is a valuable resource for data analysts as it assists in combining data, ensuring data quality, selecting appropriate analyses, and understanding the database's contents.
