I want to use COUNTIF function to evaluate how many items out of 2,0,0,5 are greater than 2? In Countif function, first argument is range and second is criteria. I have tried the below formula. Even tried using Ctrl+Shift+Enter at the end to evaluate. But doesn't seem to work.
=COUNTIF({"2","0","0","5"},">2")
COUNTIF doesn't accept array constants (as far as I know). Try this:
=SUMPRODUCT(--({2,0,0,5}>2))
You could also create a countif-style formula like this (the combination ctrl+shift+enter):
=COUNT(IF({2,0,0,5}>2,1,""))
Recommended reading: Array vs Range
Some functions like Offset, SumIf, CountIf, SumIfs, and CountIfs are designed to operate only on (multi-cell) range objects. Sum, SumProduct, Frequency, Linest, lookup functions, etc. take both range and array objects.
Array means: {2,0,0,5}
Range means:
To use countif, you have to use range in cells, defining the array in the formula on the go will not work.
=COUNTIF(A1:A4,">"&2)
