Vote staking is the reason why certain indian films were barred from
making the Top250, its unfortunate a few good films were also added to that list because of "trolls" either upvoting them (giving 10)...
Just to be curious, I unbiasedly took a look at the data into ratings.list and I have to agree with vhavnal. I do not intend to discuss the methods by which IMDB decides the titles that make the Top lists, but there is really something particular about the voting distribution in Indian films. I'll simply post here some numbers and graphs and will let everyone draw their own conclusions:


----------------- Data from ratings.list (as of 29 Jul 2016) -----------------
  • Titles with rating information: 664,637
  • FILMS AND MADE FOR VIDEO (V) TITLES: 308,588
            Number of votes:
                    Average number of votes per title: 1,881 votes
                    Median number of votes (Q1/Q3): 24 votes (10/111)
                    Mínimum number of votes: 5 votes (20,369 titles)
                    Maximum number of votes: 1,683,511 votes (The Shawshank Redemption (1994))

            Ratings:
                    Any number of votes (308,588 titles):
                            Average rating: 6.492 / Median rating: 6.600
                            Highest rating: 10.0 (426 titles)
                            Lowest rating: 1.0 (103 titles)
                    Titles with at least 1,000 votes (24,002 titles):
                            Average rating: 6.458 / Median rating: 6.600
                            Highest rating: 9.6 (Radovan III (1983) (V))
                            Lowest rating: 1.1 (Biebermania! (2011) (V))
                    Titles with at least 5,000 votes (9,764 titles):
                            Average rating: 6.641 / Median rating: 6.800
                            Highest rating: 9.5 (Hababam Sinifi (1975))
                            Lowest rating: 1.2 (Kartoffelsalat (2015))
                    Titles with at least 20,000 votes (4,478 titles):
                            Average rating: 6.771 / Median rating: 6.800
                            Highest rating: 9.5 (Hababam Sinifi (1975))
                            Lowest rating: 1.6 (Justin Bieber: Never Say Never (2011))
                    Titles with at least 100,000 votes (1,310 titles):
                            Average rating: 7.191 / Median rating: 7.200
                            Highest rating: 9.3 (The Shawshank Redemption (1994))
                            Lowest rating: 3.7 (Batman & Robin (1997))

            Distribution of votes in titles with at least 1,000 votes:
                    Average percentage of 1 estrella0 estrellas votes: 6.79%
                    Average percentage of 2 estrellas0 estrellas votes: 5.49%
                    Average percentage of 3 estrellas0 estrellas votes: 5.79%
                    Average percentage of 4 estrellas0 estrellas votes: 6.79%
                    Average percentage of 5 estrellas0 estrellas votes: 10.04%
                    Average percentage of 5 estrellas1 estrella votes: 15.79%
                    Average percentage of 5 estrellas2 estrellas votes: 20.49%
                    Average percentage of 5 estrellas3 estrellas votes: 16.71%
                    Average percentage of 5 estrellas4 estrellas votes: 9.14%
                    Average percentage of 5 estrellas5 estrellas votes: 11.85%

Therefore, the 10-star votes on average represent about 12% of all the ratings within a title. But let's describe these 10-star votes in a deeper way since there are titles with a very high percentage of 10-star votes and others with a very low one. Here's the distribution of percentages of 10-star votes among titles with at least 1,000, 5,000 and 20,000 votes respectively (note that the percentage of 10-star votes is consistently under 20% in around 90% of the titles and that the average percentage is around 11%):
  • Distribution of 10-star rating percentages:
            Titles with at least 1,000 votes (24,002 titles):


            Titles with at least 5,000 votes (9,764 titles):


            Titles with at least 20,000 votes (4,478 titles):


Finally, let's compare visually the distribution of percentages of 10-star votes by country.To make things easier, I'll ignore the 29,073 co-productions and the 795 titles with no country listed and I'll refer to the 278,720 titles with just one country of origin. I've also set a minimum of titles for every threshold of votes to ensure an acceptable level of quality in the comparison (only countries that reach that minimum limit of votes and titles are displayed in the graph).
  • Distribution of 10-star rating percentages per country:
            Countries with more than 25 titles with at least 1,000 votes:


            Countries with more than 10 titles with at least 5,000 votes:


            Countries with more than 10 titles with at least 20,000 votes:


I won't say that Romania, India or Turkey should "give some explanations", but these are real numbers from the database... Anyway, the main conclusion here is that the greatest discrimination is against Justin Bieber!! JuasJuasJuas
