According to Google, it appears someone has. Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words!Quote:

Is the standard deviation that you're talking about related to statistics or is it related to something else?Quote:

I for one appreciate Quzah's candor. It is nice to have someone to tell you the answer. But it is even better if the person can do a little work on their own. Perhaps they should have a thread that teaches research techniques on the web. I find a lot of the answers to people's questions not because I know the answer but because I looked it up. Granted if Quzah is fed up with answering question's he doesn't have to reply at all. The only problem with research on the web is that you do tend to get a variety of websites that carry information but you have to sort it all out to find what is relevant. And not all of the information is correct. I am sure there are plenty of outdated tutorials that still use #include.h and a variety of other archaic, non-standard, and outmoded snippets of code. But for the most part you can still find the answer with a little WORK. But I don't think that discouraging people who ask questions is the answer. No one is forcing you to answer the question. Has anyone ever asked you for directions at a gas station? Granted they could buy a map or an Atlas. With a little work they could arrive at their destination, but sometimes it is easier to just ask.
I wasn't complaining. They both provide correct information, and they both make me snicker while doing so. I rather like it.
The square root at the end doesn't take time proportional to the number of elements. So I think what's going to slow the calculation is finding the mean and the summation of the squares of differences.
I agree with this. I am still a begginer and all to often people tell me to google for the answer or clues to the answer. But the biggest problem us newbs face is knowing 'what to google for'.Quote:
