Interpretation
 Gross- Mean value of gross revenue is 65.93 and value of median is 26.82. It means that on
average basis, revenue of 65.93 million USD is earned by the business firms. Moreover,
26.82 million USD is the medium value of total amount of revenue earned by business
firms. There is no value of the revenue that is repeating multiple times in data set. Hence,
value of mode is NA. Standard deviation is equivalent to 111.866 which means that by
higher amount, revenue of different movies deviate from mean value.
 Theatres- From the above table, it can be observed that value of mode is 3003. This means
that most of the movies are released in 3003 theaters. Mean value is 2460 and it is reflecting
that on average basis, films are screened on mentioned number of theaters. Standard
deviation value is quite high which indicates that there is huge difference among the movies
in terms of their release on specific number of theater screens.
 Metacritic- On an average, films are receiving rating of 54.71 from views. Statistics indicate
that most often, viewers give a rating of 81 to most of the movies that are in data set. Value
of standard deviation is very low which means that maximum movies get similar ratings
from viewers.
 Sequel/Reboot- There are very small values of mean and standard deviation. Value of
median and mode is zero. This reflects that sequel parts of most of the movies are not
prepared.
 Action- Trends that were observed in the sequel are again repeating in the action. Hence, it
can be said that less action movies are screened in theaters of USA.
