mean, median, mode in SQL Server Reporting Services

Question

Is it possible to calculate an mean, median, mode, standard deviation, etc. of a column of data?

In general, is it possible to do these sorts of math calculations i

Answer 1

Here is Median() From Report Design Tips and Tricks...

Scenario 1

1: In Report Designer, open the Report Properties dialog box and click the Code tab. Define an array, a function that takes a value and adds it to the array, and a function that calculates the median value from the array;

Dim values As New SystemCollections.ArrayList

Function AddValue(newValue As Decimal) As Decimal
   values.Add(newValue)
   AddValue = newValue
End Function

Function GetMedian() As Decimal
   Dim count As Integer = values.Count
   If (count > 0)
      values.Sort()
      GetMedian = values(count\2)
   End If
End Function

2: Wrap the call to the function in an aggregate and add it to an expression in the detail rows.

=Max(Code.AddValue(Fields!field.Name))

3: From a text box in the table footer, call into GetMedian() to retrieve the value

=Code.GetMedian()
