1. Excel calculates the maximum and minimum values in a column, which are expressed in red and green, and calculates the average value of the number except the maximum and minimum values There is a group of numbers from A1 to a10. Among these numbers, if it is the largest, red will be displayed, if it is the smallest, green will be displayed, and the average value of A1 to A10 will be displayed on a11. However, the average value is the average value after removing the maximum value and the minimum value. That is: add the other 8 numbers and divide by 8 Is it impossible? Wodaxiaopengyo: please explain the meaning of "= $A1" in "= $A1 = max ($a $1: $a $10)", because I can get the correct result only by inputting "= max ($a $1: $a $10)" In addition, the formula behind you is really wonderful. I use the following formula: obviously not as good as yours =(SUM(A1:A10)-MAX(A1:A10)-MIN(A1:A10))/(COUNT(A1:A10)-2) Thirdly, after entering the above formula, if you use Ctrl + Shift + enter to end, a synthesis bracket will appear, but the result will not be affected,
