I have three columns of data that are identical. They all are numbered 1 through 30. I need each row to average out as close to 15 as possible. Each number (1 through 30) can only be used once in each column.
Example with only 3 numbers in each column with each row averaging 2.
1 3 2 Avg 2
2 1 3 Avg 2
3 2 1 Avg 2
Easy with just 3 numbers. Can't really figure it out manually with 30 numbers in each column. Is there a formula I can use to figure this out?
