Common scenarios

Whatever your data, start by describing the question

Surveys & scalesCollected survey data but unsure where to start? Reliability, validity, group differences, regression — describe the goal to get an analysis plan.
Thesis & course projectsStuck on the data-analysis part of your project? From method selection to formatted result tables, confirm each step as you go.
Medical & clinical dataSurvival analysis, ROC curves, and logistic regression without digging through tutorials — run clinical data right in the browser.
Economics & management researchPanel regression, DID, and PSM — empirical methods you would run in Stata, done on the web.

How it works

Three clear steps from data to results

The AI works through the question before running the analysis. You can review each decision instead of relying on a hidden black box.

01

Upload data

Choose an Excel, CSV, SPSS .sav, or Stata .dta file, or start with sample data to understand the workflow.

02

Describe the question

Explain the data context and what you want to learn; the AI lists method options and the conditions each one needs.

03

Confirm, run, and review

Confirm the method, run the analysis, and inspect tables and explanations; copy them or export Word / PDF, then verify against the source data and professional requirements.

FAQ

What you may want to know before starting

Short answers about usage, supported files, result review, and data handling.

Is ChatSRS the official SPSS site or an installer download site?

No. ChatSRS is an independent browser-based statistics tool and does not provide SPSS installers. You can upload SPSS .sav data and run common analyses in your browser.

Which data files are supported?

The current interface supports Excel, CSV, SPSS .sav, and Stata .dta files. Refer to the upload screen for current structure and size limits.

Can I use it if I am not confident with statistics?

You can describe the data and goal first, then review the AI's proposed workflow and method options. Study-design and professional decisions should still be confirmed by you or a qualified reviewer.

Can I use AI results without checking them?

No. Review AI output against the source data, variable definitions, study design, and professional requirements. ChatSRS does not replace your final judgment.

How is data stored and processed?

The site uses HTTPS. Collection, retention, and third-party processing are described in the current privacy policy; remove unnecessary direct identifiers before uploading data.

How much free quota is included?

Free quota is available after registration. Your account page shows the current amount and reset time so this page does not become outdated when rules change.
