I was looking at my CleanPalette comments this morning and noticed the rating currently sits at 4. SO I thought, if I do my calculations based on only ONE person voting me 1 and the rest voting 5 and calculated the mean average, when would it equal 5 again?

My calculations are currently at 10,000,000 (that’s 10 million) votes and the mean average still DOES NOT equate to 5. This made me a little concerned since the mean is the most commonly-used type of average.

My calculation – if 9,999,999 people voted 5 and 1 person voted 1
total vote points: 9,999,999 * 5 + 1 = 49,999,996
num of votes: 9,999,999 + 1 = 10,000,000

MEAN AVERAGE : 49,999,996 / 10,000,000 = 4.9999996

It does not necessarily mean that my template has only one vote of 1 and the rest are 5 but if someone is in this situation and the mean is the average equation being used then it seems unlikely they will ever have an average rating of 5 again.

I think it is pretty clear that when 9,999,999 people vote 5 and only one person votes a 1, the average rating really should be 5, not 4.

Therefore, I wanted to ask… does the rating logic on TF ever round up after, say, an average of 4.51? or does it wait until the average is 5 (as described in my calculations)?

P.S. Sorry for such a long message! Haha

I think it rounds up after 4.5. It doesn’t make sense the way you described because you can never have complete five if only one vote is less than five.

I don’t know for sure, but I would assume that a system that would prevent a rating of 5, unless EVERY vote was 5. Would be a bit counter productive. I’m assuming theres a margin for the system to round up.

As far as I learned, according to “the rules of rounding numbers” 0.5 should be rounded up. So 4.4999 becomes 4 and 4.5000 and higher become 5.
