User talk:Nk28

Welcome
Hello, Nk28, and welcome to Wikipedia! Thank you for your contributions. I hope you like the place and decide to stay. Unfortunately, one or more of your edits to the page Algorithms for calculating variance have not conformed to Wikipedia's verifiability policy, and have been reverted. Wikipedia articles should refer only to facts and interpretations that have been stated in print or on reputable websites or other forms of media. Always remember to provide a reliable source for quotations and for any material that is likely to be challenged, or it may be removed. Wikipedia also has a related policy against including original research in articles.

If you are stuck and looking for help, please see the guide for citing sources or come to the new contributors' help page, where experienced Wikipedians can answer any queries you have! Or, you can just type   on your user page, and someone will show up shortly to answer your questions. Here are a few other good links for newcomers:
