Petersburg, IL | I use a little bit of statistical analysis to aid in cleaning yield data. I go to edit legend. I write down the mean and the standard deviation. I then take the standard deviation and multiply by 3. I then take that number and add it to the mean, write that down, then subtract it from the mean. Those two numbers are then used in the edit layer screen as filters. Its a long process but I think it cleans the data nicely without too much arbitrary selection of points. | |
