Frequently Asked Questions

Are these online statistical calculators accurate for research?

Yes. All calculators on this site are developed and tested by Yohay (with AI assistance), a statistician with an M.B.A. from The Tel Aviv academic college, and B.A. from Hebrew University. The algorithms are rigorous and validated against industry-standard software like R, SPSS, and Excel to ensure high precision for academic and professional use.

How do I cite this statistical calculator in APA or MLA?

We appreciate the credit! Citing the tool ensures reproducibility in your research. In APA format, you can generally use:
Statistical Calculators. (Year). [Name of Specific Calculator]. Retrieved [Date], from [URL].

Is this site a free alternative to SPSS, R, or Excel?

Yes. With over 250 calculators, this site allows you to perform specific tasks—such as hypothesis testing, confidence intervals, and regression analysis—directly in your browser without purchasing expensive software licenses or writing code.

Is my data safe? Do you store the data entered?

No. Your privacy is paramount. Calculations are performed "client-side" (in your browser) or processed temporarily and immediately discarded. We do not store, sell, or analyze your raw datasets.

Why am I getting a "NaN" or Error result?

This is usually a formatting issue. Ensure you are entering raw data separated by commas or spaces, and avoid non-numeric characters. Also, verify that your sample size (n) is sufficient for the specific test you are running.
