Terms of Service

Last updated: October 2026

These terms govern your use of stdbee.com (the "Site"). By using the Site you accept them. If you do not, please do not use the Site.

The tool this page covers is StdBee, a standard deviation calculator. Put simply, it computes population and sample standard deviation, variance, mean and count from a batch of numbers, with input cleaning and step-by-step working, and the way it does so is this: it distinguishes the population and sample formulas by the divisor — N or N-1 — which is the difference that makes a sample estimate slightly larger, and shows each step so the arithmetic can be followed. Everything stated here applies to that tool and the values it handles, and to nothing else.

Practically, all the calculation needs is the data you paste. Typical reasons people open StdBee include checking the spread of a set of measurements, and in every case the work happens on the visitor's own device rather than ours.

About this Site and its tools

The Site provides a standard deviation calculator and explanatory material, free of charge, for general information and education. Results are estimates derived from the inputs you supply using the method described on the page. Results are offered for general information and convenience, and anything that matters should be verified independently.

No professional relationship

Using this Site does not establish a professional relationship with us, and no result should be treated as professional advice. The judgement about how to use it is yours.

Errors and completeness

We aim to be correct and to say how the result is produced. That is not a warranty: results may contain mistakes and the material may fall out of date. Treat any figure with a known margin as an estimate.

What you may and may not do

The Site is available for your own personal or business use. Do not attack, overload, or scrape it to the point of harming other users, do not pass it off as your own work, and do not use it for anything illegal.

Intellectual property

Unless credited otherwise, the Site's design, writing and code are ours or used under license. Linking to any page is welcome; copying large portions of the content needs our written consent.

Third-party content and advertising

Third-party adverts keep the Site free and external links appear for convenience. We vouch for neither, and neither can change an output.

Availability

We make no guarantee the Site will always be available. Any tool or page may be changed or removed at any time, and the service is supplied "as is".

Liability

To the extent the law allows, we are not liable for consequential or indirect damages, nor for choices made on the strength of an output here.

Which law applies

These terms are subject to the laws of the Site operator's jurisdiction, and conflict-of-law provisions do not override that.

Verifying a result

The tools give a quick general answer rather than an authoritative one. Where the outcome of a decision matters, confirm it independently.
