How to average numbers with high standard deviation

85 Views Asked by At

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

One solution is to use the median instead, which is resistant to outliers. For your data, the median is $0.6846.
