How do you remove duplicate values in a dataset?

• A. Data > Remove Duplicates
• B. Data > Filter
• C. Home > Clear
• D. Insert > Chart

Answer: (D)

To remove duplicates, you identify identical rows and keep only one copy. In Excel, use the Remove Duplicates command under the Data tab. First select the data range, then click Remove Duplicates and choose which columns to inspect for duplicates. The tool keeps the first occurrence of each set of duplicates and deletes the rest, leaving a dataset of unique rows. You can choose to check all columns (treat each row as a duplicate only if every column matches) or just specific columns. The other options shown don’t perform this operation: filtering hides non-matching rows but doesn’t delete duplicates; Clear removes contents; Chart is for visualization.
