What does an IMDB / Internet Movie Database rating
mean?
User ratings of films. As one adjunct to data, the
IMDb offers a rating scale that allows users to rate films on a scale of one to
ten. ... IMDb indicates that submitted ratings are filtered and weighted in
various ways in order to produce a weighted mean that is displayed for each
film, series, and so on.
All the registered members of IMDb can cast their
votes/ratings for any movie. IMDb takes all the individual votes cast by the
registered users and uses them to calculate a single rating. The rating
displayed on a movie's page is a weighted average rating.
IMDB use their own algorithm to determine the number
of votes and their quality. The number of votes influences IMDb rating scheme.
However, before IMDb calculates the final rating of a movie, each cast vote is
keenly evaluated. Though each cast vote is used to compute a single rating,
IMDb does not determine the results based on mean or average votes but on
weighted average instead. The evaluation of each vote is to help IMDb identify
who voted.
Despite the fact that IMDb displays all the votes
cast, for an IMDb vote to count, it has to be from a registered user. To make
sure the voting process is fair to all, a registered user is only allowed to
rate a movie once. Besides, users have a right to make changes when they wish
to.
In case an IMDb user updates the rating on a particular
film, the new rating overwrites the previous one. This is the reason why most
movie rating goes down without showing any change in the number of votes.
User ratings of films
It has been alleged that the rating system is flawed,
for several reasons.
IMDb indicates that submitted ratings are filtered
and weighted in various ways in order to produce a weighted mean that is
displayed for each film, series, and so on. It states that filters are used to
avoid ballot stuffing; the method is not described in detail to avoid attempts
to circumvent it. In fact, it sometimes produces an extreme difference between
the weighted average and the arithmetic mean.
Rankings
The IMDb Top 250 is a list of the top rated 250
films, based on ratings by the registered users of the website using the
methods described. As of 7 February 2019, The Shawshank Redemption is #1 on the
list. The "Top 250" rating is based on only the ratings of
"regular voters". The number of votes a registered user would have to
make to be considered as a user who votes regularly has been kept secret. IMDb
has stated that to maintain the effectiveness of the Top 250 list they "deliberately
do not disclose the criteria used for a person to be counted as a regular
voter". In addition to other weightings, the Top 250 films are also based
on a weighted rating formula referred to in actuarial science as a credibility
formula. This label arises because a statistic is taken to be more credible the
greater the number of individual pieces of information; in this case from
eligible users who submit ratings. Although the current formula is not
disclosed, IMDb originally used the following formula to calculate their
weighted rating.
The IMDb also has a Bottom 100 feature which is
assembled through a similar process although only 1500 votes must be received
to qualify for the list.
The Top 250 list comprises a wide range of feature
films, including major releases, cult films, independent films, critically
acclaimed films, silent films, and non-English language films. Documentaries,
short films and TV episodes are not currently included.
Since 2015, there has been a Top 250 list devoted to
ranking television shows.
