Calculating median using two columns - excel

Question

I have the following columns
12 A
11 M
12 B
12 C
11 A
9 M
13 N
11 M
12 C
11 B
15 M
I want to calculate median based on only Ms. I have done by selecting ranges.
I want to use columns rather than ranges. Is there any solution? Thanks for your help

Answer 1

If you have 2010 or later use this formula:
=AGGREGATE(17,6,(A:A/(B:B="M")),2)
If you have 2007 or earlier, try this array formula:
=MEDIAN(IF(B:B="M",A:A))
This is an array formula and must be confirmed with Ctrl-Shift-Enter.
Though the use of full column references will slow the calculation times because it will iterate through all the rows, all 1.04 million. It is good practice to limit the references to the max data range to help offset this drain. Change the C:C to something like $C$1:$C$10000 then it will loop only 10,000 times.

Well as a VBA user I love to use VBA, other can use your skill using formulas, and is completly right if you are good on formulas. Here is my answer and I hope help you.
Imagine you have this:
+----+------------+--------------------+---------------+
| 1 | Values (A) | Criteria Range (B) | Criteria ( C) |
+----+------------+--------------------+---------------+
| 2 | 14 | B | A |
| 3 | 1 | M | |
| 4 | 15 | A | |
| 5 | 15 | E | |
| 6 | 10 | A | |
| 7 | 3 | M | |
| 8 | 11 | A | |
| 9 | 8 | M | |
| 10 | 14 | A | |
| 11 | 5 | M | |
| 12 | 9 | M | |
| 13 | 10 | M | |
| 14 | 11 | N | |
| 15 | 9 | A | |
| 16 | 2 | M | |
| 17 | 15 | M | |
| 18 | 11 | A | |
| 19 | 12 | S | |
| 20 | 9 | M | |
| 21 | 11 | A | |
| 22 | 15 | V | |
+----+------------+--------------------+---------------+
And inside the cell E2 you have this =MedianIf($A$2:$A$22,$B$2:$B$22,C2) and the result must be 11
Because in a regular module of VBA you put this function.
Function MEDIANIF(RangeIf As Range, Criteria_Range1 As Range, Criteria1 As String) As Double
Dim i
Dim Counter
Dim tmp()
Dim subCouter
subCouter = 0
For Each i In Criteria_Range1
Counter = Counter + 1
If i.Value = Criteria1 Then
subCouter = subCouter + 1
ReDim Preserve tmp(1 To subCouter)
tmp(subCouter) = RangeIf(Counter)
End If
Next i
Dim a
MEDIANIF = Application.WorksheetFunction.Median(tmp())
End Function
And the function works like this:
RangeIF = is the range with the values that you want to get the MEDIAN
Criteria_Range1 = Is the range where you have all the criteria, is the same size as RangeIF
Criteria1 = Is the criteria you use to filter the data.

Answer 3

How about this low-tech solution:
In Column C, formulate: =IF(B2="M",A2,"") (in rows 2-12, based on your data, and assuming row 1 contains headers)
In cell D2 (or anywhere else), formulate: =MEDIAN(C:C)
