Standard Deviation
Standard Deviation is a free online Math & Statistics tool that computes the standard deviation of a number list. If an item in the string is not a number it is excluded from the list. e.g. 0x0a 8 .5 becomes 4.089281382128433 instantly in your browser. Paste your data, adjust the options and get the result in real time — no installation, no sign-up, and nothing is ever uploaded to a server.
