Question

Investigating Hollywood Movies

In the following exercise, we use data from HollywoodMovies. The dataset includes information on all movies to come out of Hollywood between 2007 and 2013. Do Audience Ratings Differ Based on the Genre of the Movie
The dataset Hollywood Movies includes a quantitative variable on the AudienceScore of the movie as well as a categorical variable classifying each movie by its Genre. The computer output below gives summary statistics for audience ratings based on genre for movies made in 2011, using four of the possible genres.
Variable Genre N Mean StDev Minimum Q1 Median Q3 Maximum
AudienceScore Action 32 58.63 18.39 32.00 44.50 51.00 78.00 93.00
Comedy 27 59.11 15.68 31.00 48.00 58.00 71.00 93.00
Drama 21 72.10 14.55 46.00 59.00 72.00 84.50 91.00
Horror 17 48.65 15.88 25.00 34.00 52.00 60.50 78.00
A) Which genre has the highest mean audience score?
B) Calculate the difference in mean score between comedies and horror movies, and give notation with your answer, using Ic for the mean comedy score and Iy for the mean horror score.
C) In which genre is the lowest score, and what is that score? In which genre is the highest score, and what is that score?

Answer 1

a. Genre with highest mean is drama. Mean is 72.10

B. 10.46 is difference between means of comedy and horror

C. Horror has the lowest minimum value at 25.00

Action and comedy both have the highest maximum value at 93.00

Explanation:

First create a table with the data provided like I did in the attachment. It would give a clearer picture of what your answers should be.

1. Which genre has the highest mean score?

From the table, we have the means as:

Action = 58.63

Comedy = 59.11

Drama = 72.10

Horror = 48.65

The genre with the highest score is drama at 72.10

2. Difference in mean score between comedy and horror

Mean of comedy = lc = 59.11

Mean of horror = ly = 48.65

Difference = lc-ly

= 59.11 - 48.65

= 10.46

3. The genre with lowest score is the genre with the lowest minimum value. This genre is horror and the lowest minimum is 25.00

The genre with highest minimum value is that whose maximum value is the highest out of all the genres. Both action and comedy have the highest maximum value at 93.00
