Count Duplicate Numbers

[farid2001]

Hello
I would really appreciate some help here.
I want to count duplicate numbers based on a time spam.
I've already got the duplicate dialed number Count using:
{=(COUNT(B2:B10))-SUM(IF(FREQUENCY(B2:B10,B2:B10)>0,1))}
Also I am already able to get Duplicate dialed number Count by Location.

This is what I have:

Call Date/Time Number Dialed Location Duration
09/09 22:37:36 17204355125 Denver, CO 813
09/09 22:25:24 17204355125 Denver, CO 111
09/09 22:09:09 17204355125 Denver, CO 951
09/09 22:07:08 17725710557 Sebastian, FL 57
09/09 21:03:20 13018467933 Frederick, MD 57
09/09 20:41:52 17725711815 Sebastian, FL 532
09/09 20:36:21 17725710557 Sebastian, FL 9
09/09 20:35:31 17725710557 Sebastian, FL 29
09/09 20:34:33 17725710418 Sebastian, FL 1

For example in this situation we have that 17725710557 and 17204355125 were
dialed 3 times each, but what I need to count as duplicate is only if the
same number is dialed 120 seconds or less from the time the previous call to
that same number was over.

I know its a real tough situation, can it be done?

Hi,

Assume your data is on range A1:E10. In cell B16, type 00:02:00. In A13,
type 17725710557. Now in B13, enter the following array formula

=SUMPRODUCT(($C$2:$C$10=$A13)*($B$2:$B$10-MIN(IF(($C$2:$C$10=$A13)*($B$2:$B$10),$B$2:$B$10))>=$B$16))

Enter 17204355125 in cell A14 and coy the formula down.

Please let me know how this works for you.

Maybe =SUM(IF(B3:B11=B2:B10,IF(A3:A11-A2:A10<=120,1,0),0))
as an array formula confirmed with Ctrl+Shift+Enter.

Hello Stefi & Ashish

Thank you very much for your help, you guys are fantastic!!!

This is what I did:

39703.52331 115112324742 Peru-Lima 0.021527778 DUP
39703.54525 115112324742 Peru-Lima 0.000694444
39703.865 115112324742 Peru-Lima 0.001388889
39704.46297 115112324742 Peru-Lima 0.007638889
39704.79645 115112324742 Peru-Lima 0.006944444
39704.84566 115112324742 Peru-Lima 0.000694444
39704.8647 115112324742 Peru-Lima 0.004861111
39705.47488 115112324742 Peru-Lima 0.011805556 DUP
39705.48708 115112324742 Peru-Lima 0.003472222
39706.49169 115112324742 Peru-Lima 0.001909722 DUP
39706.49395 115112324742 Peru-Lima 0.000694444 DUP
39706.49535 115112324742 Peru-Lima 0.007638889

I converted both Call Date/Time and Duration columns into Values and after
sorting columns I used following formula:

=IF(AND(B2=B3,A3-(A2+D2)<=0.001888),"DUP","")
and it worked perfectly!

Thanks & regards
