Hello, I'm Materialscientist. Your recent edit to the page Standard deviation appears to have added incorrect information, so I have removed it for now. If you believe the information was correct, please cite a reliable source or discuss your change on the article's talk page. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Materialscientist (talk) 21:50, 1 September 2016 (UTC)
