问题
I am trying to use COUNTIF in Excel to find how many items in a range match the contents of a separate cell. The idea is, the range contains everyone's answers to a given question (a one-word, non-numeric answer); the comparison column contains the correct answer. I want a count of how many people got the answer correct.
I tried: =COUNTIF(C16:BT16,"=BU16")
But it appears COUNTIF won't let me reference a cell with the criteria in it -- it requires the match criteria directly in the formula, such as =COUNTIF(C16:BT16,"DEN"). I can do that, of course, but I'd have to edit dozens of formulas every time I evaluate answers, and it would be much less timeconsuming if I could just enter the answers in column BU.
I also tried COUNTIFS; it allows multiple criteria, but also doesn't allow referencing the criteria to a different cell. Searched several different Excel websites too, any suggestions? Many thanks!
回答1:
Try removing the quotes and equal sign from "=BU18" - that will indicate that you are passing the value at that cell, which I believe is what you're looking for.
=COUNTIF(C16:BT16,BU18)
Assuming BU18 contains DEN. Your first example ("=BU18") is saying "count if any of these cells have a value of "=BU18", which won't match anything (unless they answered some weird questions :) ).

Try this:
=COUNTIF(C16:BT16;BU18)
Please note that you may need to use ";" instead of "," depending on your region.

If you are using Excel 2010, you are even luckier with COUNTIFS
By all means you may use the search range and matching range within countif
e.g.
=COUNTIF(SEARCH RANGE, CRITERIA RANGE)
