Authors & Team
A small team builds and checks RSD Calculator. We are engineers, statisticians, and former lab scientists. Every formula, example, and article here is written by one of us. Another one of us then checks it.
-
Engineering
Builds and maintains the calculators, keeps every page fast, and ships the step-by-step working shown on each result.
-
Statistics Review
Checks every formula and worked example against reference sources before it ships, and reviews reader-reported corrections.
-
Content & Education
Writes the blog and the guides, turning reference statistics texts into plain, practical explanations.
Editorial Standards
We publish only what we can stand behind. Each calculator shows the formula it uses. It also shows each step, so you can check the answer yourself. Our articles cite trusted sources such as the NIST/SEMATECH e-Handbook of Statistical Methods. Found a mistake? Want to reach one of us? Email contact@rsdcalculator.com and a real person will read it.
