How do I aggregate data across multiple worksheets in excel?

Question

I've been trying to figure this out for some time now. We utilize the same evaluation through survey monkey for every one of our training sessions. There are 8 questions in total. For a single survey, we get the results back in an excel format with the data spread across 8 separate work sheets. What I would like to have is a formula that can be used to aggregate the data for each one of the questions across multiple spreadsheets.

For example, we want to know the average response for Question #1 from the training sessions for client ABC, DEF and HIJ. Hope that makes sense.

Question 1

Question 2

Answer 1

Have you tried something as simple as:

=SUM('Question 1:Question 8'!A1)

where A1 is the cell of interest on each sheet?

If you can put whatever result you want per question in the same cell on each sheet of the workbooks, you can use SUM over the range of sheets.
