Can someone explain to me why TI-92 gives me the wrong answer for standard deviation. I put in: stdDev({4,7,10,11,12,14,15,21,32}) and I get 8.30662 but the answer is 7.83 Try to keep in mind I kinda new at using a TI-92. So, why do I get 8.31 instead of 7.83 Mike ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
