averaging a column of letter grades into a numeric GPA
In my spreadsheet, column A contains letter grades (A, A, B+, etc.). I have
a GPA reference table in F1:G11, with F1="A", G1=4; F2="A", G2=3.67; and so forth. Now, I know how to use VLOOKUP to turn an individual letter grade into a GPA value. In B2, I have the formula =VLOOKUP(A2,$F$1:$G$11,2,FALSE), and that works fine. What I want to do is to find the average GPA value of all the letter grades in column A. That's easy if I create a new column of data, column B, containing copies of the formula given above. But I don't want that intermediate step. How can I get the average GPA value without creating a new column of data? Many thanks.

Try this...
=SUMPRODUCT(SUMIF(F1:F5,A1:A10,G1:G5))/COUNTA(A1:A10)  Biff Microsoft Excel MVP "David Aukerman" > wrote in message ... > In my spreadsheet, column A contains letter grades (A, A, B+, etc.).

Use the AVERAGE function and select the range of cells containing the converted grades (that is the VLOOKUPs).

Daryl,
That would do it, but I don't want to have a column of converted grades. Biff's solution above is more what I was looking for.
