Conditional COUNTIF using logicals

Conditional COUNTIF using logicals

Conditional COUNTIF using logicals

(OP)
I have an array of 8760 hourly data kW readings for a year (24 by 365).  I want to count the number of hours >= 15000 this works but then using and the AND logical it does not work.  Here is formula that does not work  =countif(D4:AA368), (AND>14900, (D4:AA368)<=15000)) it gives me zero.  

Can someone please help me out with this feature?  

RE: Conditional COUNTIF using logicals

Won't the AND function have a problem with the a range comparision?  Could you add an additional column that puts a 1 or 0 in next to the cell, and just reference 2 different cells to create your limit criteria?  For example:

Assume D1 contains the minimum value (14900), and D2 contains the max value (15000).

=if(AND(D4>$D$1,D4<=$D$2),1,0)

Then just copy the formula, and sum the results?

RE: Conditional COUNTIF using logicals

CountIf doesn't seem to like logical operators in its Criteria argument.

You could always use a Macro:

Sub Macro1()
Dim c As Range
Dim x As Range
Set x = Sheet1.Range("D4:AA368")
For Each c In x
If c.Value <= 15000 And c.Value > 14900 Then
q = q + 1
End If
Next c
Sheet1.Range("a1").Value = q
End Sub

Good Luck

RE: Conditional COUNTIF using logicals

Use the following as an array formula.

SUM(IF(C3:C8762>15000,1,0))

Array function?  Use <crtl>-<shift>-<enter> rather than just <enter> when you have finished typing the formula.  The formula will then appear as if you typed it with {braces} around it.

For greater flexibility, you can put your threshold value of 15000 into a cell and reference that cell in the IF function.

RE: Conditional COUNTIF using logicals

Why not COUNTIF(D4:AA368,">=15000")?  If you want to make the criteria general, say entering 15000 in cell A1, then use COUNTIF(D4:AA368,">="&TEXT(A1,"##")).  This isn't an array formula and you don't need to use Ctrl-shft-enter.

RE: Conditional COUNTIF using logicals

or COUNTIF(D4:AA368,">14900")-COUNTIF(D4:AA368,">15000")

Can also use the frequency function.
