I was given an assignment dealing with finding standard deviation. From the example given, I was able to do the assignment and get the correct answers, but I still don't understand standard deviation or its importance.(adsbygoogle = window.adsbygoogle || []).push({});

Could someone explain standard deviation to me, or at least point me to a good site that can explain the concept? Thanks.
