Remove outliers from data set
Randy Lerch 1979 topps, card #52 is listed with an average value of $46.54. I am new to this so maybe I don't know how to eliminate outliers from your data set using your system, but this card for example is listing a $3000.00 sale in the data set...that data point is a huge outlier. When you do the math and eliminate outliers the value is $23.13...not $46.54. Just an observation...

Hi Bmwright69,

Thank you for your feedback.

I can't see any error report submitted under the username Bmwright69 so I'm not sure what you mean when you say you eliminated outliers.

The $3,000 sale was incorrectly on this chart, I have updated the database and correct this now.

Please let me know if you spot any more errors.

Many thanks,

Tom.
