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...

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.
