{SUM(IF(...} To SUMIF(...)
Apr 4, 2009I have a workbook which I am trying to clean up and make more efficient (in terms of formula calculating time).
In it are examples of array formula such as this one (which work correctly):
{=SUM(IF(Expected!$A7:$A894=5,Expected!$K7:$O894))/3}
From past readings here, I have heard that the array {SUM(IF(...} is slower in calculating than the SUMIF(...) equivalent.
As such i tried to convert is to:
=SUMIF(Expected!$A7:$A894,5,Expected!$K7:$O894)/3
This gives a different answer though. I thought for a single criteria they would be equivalent.
Q1: What am I doing incorrectly above?
Q2: Is there a more efficient version of the array formula I could use (SUMIF and otherwise), so I can have some options availible.
