Using an expression to AVG a tables column contents

Is there a way for me to use an expression on a label to display the average of a tables column data, regardless of row count?

My example, my table return this:

The table could several more rows beside the 3 listed here. I would like to take the column Avg_Eff and then average it for an Overall_avg., then display that value in a label.

Thank you
