Try one of these...

All versions of Excel, array entered**:

=AVERAGE(IF(A1:A7="EDCP",B1:B7))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

Format as [h]:mm

Excel 2007 only, normally entered:

=AVERAGEIF(A1:A7,"EDCP",B1:B7)

Format as [h]:mm

I need to average the cells on column b that correspond to the criteria in
column a. If cells in column a match "EDCP", average the cells in column b
that correspond to those cells, not the whole column. In this case it
would
equal 00:30. I will appreciate your help.

Order Procedure Drawn to Received
EDCP 0:06
CBCsD 0:06
UA 0:16
EDCP 0:59
CBCsD 0:59
Troponin-I 0:59
EDCP 0:25
