# How to review pay outliers

## Applies to: Admins and Pay Users

You can review your most extreme pay outliers to check whether a reported pay gap reflects a genuine pay difference or a data quality issue that needs correcting.

### **Solution overview**

To review outliers, navigate to the **People** tab under Pay, then use the *Filter outliers* control to show low and high outliers and sort by compa ratio.

#### Step 1: Review the outliers

1. Select the **People** tab under the Pay section from the left-hand menu.  
   ![people](https://knowledge.skillstrust.org/hs-fs/hubfs/people.png?width=208&height=492&name=people.png)
2. Open **Filters** and set *Filter outliers* to **Low Outliers**.

3. Sort the **Compa Ratio** column lowest first.  
   ![compa ratio filter](https://knowledge.skillstrust.org/hs-fs/hubfs/compa%20ratio%20filter.png?width=670&height=147&name=compa%20ratio%20filter.png)
4. Start with the 10 lowest, as a manageable first pass. You can work through more once you have dealt with the most extreme cases.
5. Change *Filter outliers* to **High Outliers**.
6. Sort the **Compa Ratio** column highest first, and review the first 10 records.

**Compa ratio and outlier status**

The **compa ratio** is a measure of how an employee's pay compares to the median pay for their job category.

- **1.0** - paid at the median
- **Below 1.0** - paid below the median
- **Above 1.0** - paid above the median

An **Outlier** is defined as any employee with a compa ratio less than 0.8 (low outlier) or greater than 1.2 (high outlier).

#### Step 2: Add notes to employees' records

1. To open an employee's record, click the arrow on the right of their row.  
   ![open employee record](https://knowledge.skillstrust.org/hs-fs/hubfs/open%20employee%20record.png?width=670&height=104&name=open%20employee%20record.png)
2. To add a note, click **Edit** in the top right, type your note, then click **Save**.   
   ![edit employee record](https://knowledge.skillstrust.org/hs-fs/hubfs/edit%20employee%20record.png?width=670&height=253&name=edit%20employee%20record.png)  
   ![note](https://knowledge.skillstrust.org/hs-fs/hubfs/note.png?width=670&height=333&name=note.png)  
   ![save employee record](https://knowledge.skillstrust.org/hs-fs/hubfs/save%20employee%20record.png?width=670&height=333&name=save%20employee%20record.png)
