About This Feature

Overview

CHISQ,INV is a statistical function in WPS Office for Windows AirSheet. It returns the inverse of the right-tailed probability of the chi-squared distribution for a given probability value, helping with statistical analysis, result checking, and formula modeling in spreadsheet work.

Core capabilities include:

Entering the CHISQ,INV formula directly in a cell for calculation.
Viewing syntax prompts, parameter requirements, and examples while typing the function name.
Using cross-sheet references to pull parameters from other worksheets.
Supporting nested formulas with automatic recalculation after data changes.

System Requirements

Item	Requirement
OS	A Windows device that can run WPS Office normally
App version	The latest version of WPS Office is recommended
Network	Local formula calculation does not require a constant internet connection; download, installation, and account services require network access
Other	You need to open an AirSheet file and have permission to edit cell formulas

Download & Installation

Before using CHISQ,INV, install WPS Office on your Windows device and open WPS AirSheet.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	CHISQ,INV can be entered directly in WPS AirSheet cells, with syntax prompts, cross-sheet references, nested formulas, and automatic recalculation.	Microsoft Word supports formulas in table cells and can update results, but the feature is designed for document tables rather than a full spreadsheet function environment.	Google Sheets supports formulas and functions in cells, with a function help box, suggestions, nested functions, and range selection while editing.	Notion formulas work with database properties and functions for row-based calculations in databases rather than traditional worksheet cells.	Adobe Acrobat supports predefined and custom calculations for PDF form fields, which fits form workflows rather than spreadsheet-based statistical analysis.
WPS Advantages	Advantage: WPS keeps statistical function entry, references, and automatic recalculation inside a spreadsheet cell workflow, which fits ongoing data analysis.	Compared with WPS: formula support is available in document tables, but the workflow is centered on table fields inside Word documents.	Compared with WPS: Google Sheets also supports formula help, nested functions, and cell-based calculations; WPS documentation for this feature specifically covers CHISQ,INV prompts, cross-sheet references, and nested use in WPS AirSheet on Windows.	Compared with WPS: Notion is stronger for database property logic and workspace tracking, but it does not provide the same worksheet-style cell reference experience.	Compared with WPS: Acrobat is better suited to PDF form calculations and totals, not worksheet-based statistical formulas.

Overall Conclusion
If your work focuses on spreadsheet-based statistical formulas, WPS AirSheet is closer to a standard cell formula workflow on Windows. The other products also provide calculation features, but they are oriented more toward document tables, database properties, or PDF forms.

Use Cases

#	Scenario	Target Users	Core Pain Point	Solution
1	Reverse lookup for statistical results	Data analysts	You already know a probability value and need the corresponding statistical result quickly	Enter the CHISQ,INV formula directly in a cell
2	Multi-sheet data analysis	Finance and research users	Parameters are stored across different worksheets, so manual collection is slow	Use cross-sheet references to pull parameters
3	Compound formula modeling	Advanced spreadsheet users	A single function is not enough for the full analysis flow	Nest CHISQ,INV with other functions
4	Dynamic result updates	Users maintaining recurring reports	Results need to update after source data changes	Rely on automatic recalculation
