Yeah saw that voting tip before but wouldnt it be better if DP uses statistical mean instead of average? I think its more representative of the real score.

With relatively few votes per entry, you have very little confidence in the average ranking. For example, if photo 'A' has one vote of 5 stars, but photo 'B' has nine votes of 5 stars and one vote of 4 stars, 'A' ranks higher than 'B' on a simple average.

Perhaps you could elaborate on what you mean by "statistical mean" vs. "average". "Mean" can have different meanings (no pun intended), but generally the mean is the arithmetic average of a set of values...

Yeah that's exactly what i'm noticing on the effect of votes to the ranking of pics, a few low votes can effectively pull down a good contender from the race. One or a group can simply low vote any decent looking competition out of the challenge.

Sorry was referring to Median instead of Mean
