Go to Tables > Summary.

Specify Name and Week as the Group variables.

Click on Stipend and choose Statistics > Sum.

Click OK.

In the resulting table, add a column and indicate that it will be based on a formula.

Build your formula. Remember that the Sum(Stipend) column is your sum and the N Rows column will be the equivalent to your "COUNT" function as follows.

`1 / Log10( :Name( "Sum(Stipend)" ) / :N Rows )`

I should add that you can accomplish this without using Tables > Summary if you don't mind the repeated values from your formula evaluation. Your formula column could look like this:

`1 / Log10( Col Sum( :Stipend, :Name, :Week ) / Col Number( :Stipend, :Name, :Week ) )`
