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.
The nature of this site
The content on stdbee.com exists to inform and educate. Every result is an estimate derived from your input, not a measurement or a piece of professional advice — and StdBee makes no claim beyond that.
Quick answers, with a caveat
This is a convenience tool producing a quick answer. If the outcome matters — a measurement you will act on, a number you will submit — confirm the StdBee result by other means.
Links to other sites
Where we link to an outside source it is for reference. We do not control that content and are not responsible for its accuracy.
Advertising and independence
Adverts fund the Site and cannot influence a result. An advertisement appearing here is not an endorsement of the advertiser or the product.
No warranty
The assumption that matters most for StdBee is that your input matches the model. 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. When it does not — or when rounding, unit handling or browser behavior intervenes — no warranty attaches to the Site, careful as we are with the method.
Checking before you act
The final check is yours: make sure a result matches your situation before you rely on it. Found an error? The contact page is the fastest way to tell us.
