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.
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.
