Sometimes you want to exclude some **specific rows** of data in your dataset. This might be because: - There is something wrong with the data (you can see from the values that it's been typed in wrong, like if a person's height was set to 12 feet, but you don't know what the right value should have been). - You want to show just a subset of your data on the graph (you collected data from three classes, but only want to show for two of them) ## How do I do it? In the **TABLE tab,** click the **Excluded** checkbox at the **end of each row**: ![](https://cdn.document360.io/62f8f41e-e041-42c4-b9bc-8ae1eb45d064/Images/Documentation/image-1677420082646.png) Excluded rows are removed from all functions in the tool - graphing, calculations, everything. It's like they weren't there. ### Excluding many rows with similar values Three options to exclude: ![](https://cdn.document360.io/62f8f41e-e041-42c4-b9bc-8ae1eb45d064/Images/Documentation/Untitled%20drawing-16.png) Use a **Filter** to set the exclude checkboxes dependent on the contents of one or more columns. [See this article for details](/v1/docs/filtering-rows-of-data). ![](https://cdn.document360.io/62f8f41e-e041-42c4-b9bc-8ae1eb45d064/Images/Documentation/Untitled%20drawing-17.png) **Exclude by value** **of a Categorical** column. Open the gear icon for the column and use the Exclude tools there.
