About This Feature
Overview
TRIMMEAN is a built-in statistical function in WPS Spreadsheets on Windows. It helps you calculate the mean of the interior of a dataset after excluding a proportion of values from the high and low ends.
Core tasks include:
- Insert the TRIMMEAN function from the Insert Function dialog when you want guided function lookup and parameter entry.
- Type
=TRIMMEAN(...)directly in a cell or in the formula bar for faster formula entry. - Review syntax and parameter guidance in the function help interface before confirming the formula.
This function is useful for datasets with outliers, classroom or lab data cleanup, and business reports that need a more stable average. It helps reduce the impact of extreme values and makes formula entry easier for both new and experienced spreadsheet users.

Compare with Alternatives
| Dimension | WPS | Microsoft | Notion | Adobe | |
|---|---|---|---|---|---|
| Capability Summary | In WPS Spreadsheets, you can insert TRIMMEAN from the function dialog or type it directly in a cell, then review syntax and parameter guidance in the same worksheet workflow. | Excel provides TRIMMEAN(array, percent) to return the mean of the interior of a dataset after excluding a percentage of points from the top and bottom tails. | Google Sheets provides TRIMMEAN(data, exclude_proportion) to calculate the mean of a dataset after excluding a proportion from the high and low ends. | Notion formulas support mean and many math functions in database properties, but the official formula reference does not describe a direct trimmed-mean function equivalent to TRIMMEAN. | Acrobat supports predefined calculations such as sum, product, average, minimum, and maximum for PDF form fields, which fits form workflows rather than spreadsheet function analysis. |
| WPS Advantages | Advantage: You can complete formula entry and calculation directly in spreadsheet cells. Distinct: WPS supports both dialog-based insertion and direct formula typing in one worksheet workflow. | Compared with WPS: Excel also offers the same function name and a similar syntax, so formula logic is easy to transfer between spreadsheet environments. | Compared with WPS: Google Sheets also supports trimmed mean calculation, but it is mainly used in a browser-based spreadsheet workflow. | Compared with WPS: Notion is centered on database properties and page-based workflows rather than direct cell-by-cell spreadsheet function entry. | Compared with WPS: Acrobat calculations are designed for PDF form fields, so they are less suitable for regular spreadsheet-style batch analysis. |

Overall Conclusion
If your main task is handling outlier-sensitive averages in a spreadsheet, WPS TRIMMEAN fits well because it supports direct cell entry, guided insertion, and parameter review in one place. Microsoft Excel and Google Sheets provide closely related function support, while Notion and Adobe Acrobat are better suited to database formulas or PDF form calculations.
Use Cases
| No. | Scenario | Suitable For | Main Pain Point | How It Helps |
|---|---|---|---|---|
| 1 | Score analysis | Teachers and trainers | A few extreme scores can distort the average | Use TRIMMEAN to exclude part of the high and low values before averaging |
| 2 | Lab data cleanup | Students and research assistants | Measurement outliers affect the result | Control the exclusion proportion to get a steadier average |
| 3 | Sales reporting | Operations and finance staff | Unusual orders can skew the overall mean | Enter TRIMMEAN directly in reports for more stable analysis |
| 4 | Repeated spreadsheet models | Heavy spreadsheet users | The same formula needs to be reused across many cells | Enter the formula once and extend it by fill or copy |
| 5 | Function learning and checking | New users | Syntax and parameter order may be unclear | Use the function dialog and help entry to review the formula before confirming |
