This is my first foray into statistics and my first post here (hope I'm in the right place!) although I find it fascinating, it's also confusing!

My company uses the formula below to calculate an average.

1 2 3 4 5 6 7

23 16 3 2 0 1 3 48

23 32 9 8 6 21 99

2.06

The top line is the scale 1 to 7, 1 being completely satisfied, 7 being completely unsatisfied.

The 2nd line contains the responses from our guests (23 are completely satisfied, 16 are very satisfied and so on)

The 3rd line is the formula 1 x 23, 2 x 16, 3 x 3, 4 x 2 and so on.

The end numbers in the 2nd and 3rd lines are the sum of each line.

The figure (which I take to be an "average") 2.06 is arrived at by dividing the sum of the bottom line (99) by the sum of the 2nd line (48).

My question is;

Is this a valid way of evaluating the responses? I don't understand why it's negatively weighted (1 response in the worst category equals 7 points in comparison to 1 in the best which gives only 1 point.

I would really appreciate any help on this, as I'm pretty sure my company is doing creative statistics!

Best regards
