About This Feature

Overview

The CHIINV function in WPS Spreadsheets returns the inverse of the right-tailed probability of the chi-squared distribution based on a given probability and degrees of freedom. You can enter it directly in a cell or in the formula bar, review syntax prompts while typing, and combine it with cross-sheet references or nested formulas for statistical analysis in spreadsheets.

System Requirements

Item	Requirement
Operating system	A Windows device that can run WPS Office
App version	It is recommended to use the latest version of WPS Office
Network	No mandatory internet connection is required for local CHIINV entry and calculation
Other	You need access to WPS Spreadsheets and an editable worksheet

Download & Installation

Install WPS Office on your Windows device before using the CHIINV function.

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Provides the CHIINV statistical function in spreadsheets, with direct cell entry, formula bar input, syntax prompts, cross-sheet references, and nested formula use.	Excel provides the CHIINV function and describes it as returning the inverse of the right-tailed probability of the chi-squared distribution, while noting that it remains available for backward compatibility.	Google Sheets provides CHIINV and states that it is synonymous with `CHISQ.INV.RT`.	Notion formulas can calculate values from database properties and built-in functions, but they are not a traditional spreadsheet function library and do not provide a CHIINV spreadsheet function.	Adobe Acrobat supports calculated PDF form fields for form workflows, but it does not provide spreadsheet functions such as CHIINV.
WPS Advantages	Advantage: You can enter CHIINV directly in worksheet cells and return results in the same grid. Distinct: It fits naturally into spreadsheet-based statistical workflows with references and nested formulas.	Compared with WPS: Excel documents the same function and clearly notes its compatibility status, with guidance toward newer replacement functions.	Compared with WPS: Google Sheets supports the same function but emphasizes its equivalence to the newer `CHISQ.INV.RT` name.	Compared with WPS: Notion is better suited to database property formulas than to spreadsheet-style statistical function entry.	Compared with WPS: Adobe focuses on PDF form calculations rather than worksheet-based statistical analysis.

Overall Conclusion
WPS CHIINV is well suited to spreadsheet users who want to enter a statistical function directly in cells and combine it with other worksheet formulas on Windows. Microsoft Excel and Google Sheets are the closest alternatives for this specific function workflow, while Notion and Adobe are oriented toward database formulas or PDF form calculations instead.

Use Cases

No.	Scenario	Suitable for	Main need	How CHIINV helps
1	Back-calculating test thresholds	Data analysts	Need to derive a statistic from a known probability value	Enter CHIINV with probability and degrees of freedom in a worksheet cell
2	Teaching and practice	Teachers and students	Need to review function structure while typing	Use `=CHIINV(` in the formula bar to view syntax prompts
3	Multi-sheet analysis	Finance and research users	Results depend on values stored in other sheets	Use cross-sheet references inside CHIINV
4	Combined statistical formulas	Advanced spreadsheet users	One function alone does not cover the full workflow	Nest CHIINV inside longer formulas
5	Recalculation after data changes	Report maintainers	Results need to update when source values change	Let worksheet recalculation refresh the result automatically
