If you keep the units in mind, they are performing better on average per salesperson.

  To clarify, I meant 'both stores' as a whole. I should have made that clearer.

    That's not fair. A mean is a way to group values, in this case per salesman. Both stores are doing better per salesman! You're the one ignoring the per salesman part, which might or might not be due to "common sense". If you want to compare both stores per se, the operator you want is sum, not average.

      The point , I think is that it's an easy way to mislead, "Average employee productivity is up in all our stores!". Of course in reality it's a good idea to mix high performers in with low performers to teach them to improve.
