Solutions for Chapter 2Problem 25E: Box Office Mojo
Box Office Mojo (www.boxofficemojo.com) tracks movie ticket sales. Ticket sales (in millions of dollars) for each of the top 20 movies in 2014 and 2015 are shown in the accompanying tables.
Construct comparative dotplots of the 2014 and 2015 ticket sales data. Comment on any interesting features of the dotplots. In what ways are the distributions of the 2014 and 2015 ticket sales observations similar? In what ways are they different? (Hint: See Example 2.6.)
The given data represents that the ticket sales for each of the top 20 movies in 2014 and 2015.
Construct the comparative dotplot for the given data.
Use Minitab to get the required plot.
1. Type the data into the Minitab work sheet.
2 Go to and click ok.
3. Specify the graph variable (2014 sales, 2015 sales).
4. Click ok.
Follow the above instructions to get the required plot as shown below:
From the above plot, observe that the shape of the ticket sales distribution is positively skewed. The distribution of 2015 ticket sales is centered at $280 million, this is higher than the center of the 2014 ticket sales distribution, and it is around $230 million. The lowest ticket sales in 2014 and 2015 are approximately $150 million. The maximum ticket sales in 2014 are $350 million and in 2015 is $397 million. The difference between the lowest and highest values for 2014 sales is approximately $200 million and for 2015 sales is $800 million.
