Refer to Mini-Project Movie Data Set.

Answer following questions based on an analysis of the data: What are the mean, standard deviation, five-number summary, and interquartile range of the total gross income for each movie genre. You can create a table with these results. Based on the previous information, which genre had greater variability in total gross income? Draw a box-and-whisker plot of a movie's length of time (minutes) by genre. Are there any any outliers in the data. If so, which ones? Click the Assignment Files tab to submit your assignment.

Paper For Above instruction

Understanding the impact of statistical measures such as mean, standard deviation, five-number summary, and interquartile range is essential for making informed business decisions, especially in the context of the movie industry where gross income performance varies significantly across genres. This analysis aims to evaluate these statistical metrics for different movie genres and interpret their implications for business strategy.

Data Analysis and Results:

The initial step involves calculating the mean, standard deviation, five-number summary (minimum, first quartile, median, third quartile, maximum), and interquartile range (IQR) for the total gross income of each movie genre. These measures provide insights into the central tendency, dispersion, and overall distribution of income data across genres such as Action, Comedy, Drama, and Horror.

Based on the statistical analysis, the genre with the highest variability in total gross income can be identified by examining the standard deviation and IQR. Greater variability indicates a wider spread of income figures, which could influence business decisions related to marketing and distribution strategies.

Next, a box-and-whisker plot is constructed to visualize the distribution of the movies' duration (minutes) across different genres. This graphical representation enables easy identification of outliers—data points that fall outside the typical range of the data. If outliers exist, they are pinpointed and analyzed to understand whether they are due to exceptional movies with unusually long or short durations, or potential data anomalies.

Interpreting these statistics and visualizations helps stakeholders make strategic decisions regarding investments, marketing efforts, and the development of new films within specific genres. For example, genres with higher income variability might warrant more risk management strategies, while outliers in movie length could inform content quality or audience preferences.

In conclusion, leveraging statistical measures like mean, standard deviation, and box plots provides a comprehensive understanding of income distribution and film duration characteristics across genres. Such insights equip industry professionals with the data-driven knowledge necessary for optimizing movie production and distribution, ultimately enhancing profitability and consumer satisfaction.
