# How to average numbers with high standard deviation

I have a set of n numbers that I need to review and come up with the closet average. The set of numbers may or may not have a high standard deviation. Below is an example...

Set of numbers..

• $0.6618 •$0.6509

• $0.6835 •$0.9561

• $15.4250 (should not be averaged, out of bounds) •$15.4400 (should not be averaged, out of bounds)

• $4.7500 (should not be averaged, out of bounds) •$0.5948

• $0.6485 •$0.6856

A simple average of these numbers is \$4.0496 however my needs require me to remove the values that are way out of bounds. Ideally my average would be around$0.6973

• I do not think you want the "closet average". But even if I replace this by "closest average", it not clear what you are asking for. – Chris Godsil Jan 25 '13 at 12:58
