Motion Picture Industry “Descriptive statistics lays the foundation for all statistical knowledge, but it is not something that you should learn simply so you can use it in the distant future, it will be used now” (Hill, n.d., para. 5). Gaining an understanding of the most basic form of statistics is crucial, some of the topics that we will focus on are the measures of location, range, quartiles, standard deviation, outliers, and correlation coefficient. Taking into consideration the movie industry and data collected for a sample of 100 motion pictures produced in 20XX the goal is to build a report that contains a 5-number summary for total gross, opening gross, weeks, and theatres for individual motion pictures and provide analysis of what the descriptive statistics tell us about the industry. Determine if there are any high performance outliers in any of the four categories, based on the findings describe what method was used and category that the outlier pertains to. Finally use the correlation coefficient to show the relationship between total gross sales and each of the other three variables and present an explanation of the relationship. Descriptive Statistics “Measures of location try to capture with a single number what is typical of the data, what single number is most representative of an entire list of numbers” (Stark, 2013, para. 2). In order to help understand the large amount of data presented in the motion picture industry a summary of each of the four categories will be presented, along with an explanation of what the data informs us about within the industry. The variable of total gross sales shows how much a particular movie earned in total. The 5-number summary and the central location that were calculated b... ... middle of paper ... ...ut it is not as strong as the linear relationship between theatres and total gross. Finally, the relationship between opening gross and total gross is a very strong linear relationship based on the diagram and the correlation coefficient of .92 as this is very close to a perfect linear relationship which occurs at 1. In the real world application this means if the opening gross of a movie is high the total gross of the movie will also be high. References Anderson, D.R., Sweeney, D.J., & Williams, T.A. (2012).
