โ“ FAQ

Frequently Asked Questions

Is this calculator accurate for research papers?
Yes. All formulas are based on standard statistical methodology used in published medical and social science research. The sample size calculations follow the Lehr/Kelsey formula, effect sizes follow Cohen's conventions, and all outputs use validated statistical tables. Results are suitable for inclusion in journal submissions and thesis documentation.
What does the free plan include?
The free plan gives you 2 full calculations per day across all 5 tools. Each calculation includes the numerical result, plain-English interpretation, and report-ready wording. The limit resets every 24 hours. For unlimited access, upgrade to the Pro plan at โ‚น199/month.
Can I use these results directly in my thesis or paper?
Absolutely. The p-value guide generates APA-style reporting wording (e.g. "t(38) = 2.14, p = .032, statistically significant at ฮฑ = .05") that you can paste directly into your results section. Sample size outputs include the effect size and power assumptions as required by most journals.
Do I need to install any software?
No installation needed. The entire calculator runs in your browser โ€” on desktop, tablet, or mobile. No SPSS, R, or Python required. Just enter your values and get results instantly.
How do I cancel my Pro subscription?
You can cancel anytime from your account dashboard or by WhatsApp'ing us at 80176 23304. There are no cancellation fees. We also offer a 7-day money-back guarantee if you're not satisfied.
Is my data saved or shared?
No. All calculations happen entirely in your browser. We do not store, transmit, or share any data you enter into the calculator. Your research data stays completely private and local to your device.
