The following formula is used to calculate the Top Rated 250 titles. This formula
provides a true 'Bayesian estimate', which takes into account the number of votes each
title has received, minimum votes required to be on the list, and the mean vote for all
titles:
weighted rating (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C
Where:
R = average for the movie (mean) = (rating)
v = number of votes for the movie = (votes)
m = minimum votes required to be listed in the Top Rated 250 list (currently 25,000)
C = the mean vote across the whole report
Please be aware the
Top 250 Movie
list only includes feature films:
shorts, TV movies, miniseries and documentaries are not included in the Top 250 Movies
Chart. The Top 250 TV Shows Chart includes TV Series, but not TV episodes or Movies.
