问题
I'm using SUMPRODUCT() to calculate the p-mean of data where p=3:
=(SUMPRODUCT(E2:E99^3)/COUNT(E2:E99))^(1/3)
There are -'s mixed into the data. How can I ignore them so as not to get a value error and still get the correct answer (as if the -'s weren't there)?
回答1:
To deal with non numbers in the range use this array formula:
=(SUM(IF(ISNUMBER(E2:E99),E2:E99^3))/COUNT(E2:E99))^(1/3)
Being an array formula it must be confirmed with Ctrl-Shift-Enter instead of Enter when exiting edit mode.
