Project Two Guidelines And Rubricscenarioyou Are A Data Analyst For A

You are a data analyst for a basketball team. You have found a large set of historical data, and are working to analyze and find patterns in the data set. The coach of the team and your management have requested that you perform several hypothesis tests to find the statistical significance of the claims that are being made about your team. This analysis will provide evidence to validate critical claims and get statistically valid findings that will help make key decisions to make the team better in upcoming seasons. You will use the Python programming language to perform statistical analysis and will also need to present a report of your findings to the team’s management.

Since the managers are not data analysts, you will need to interpret your findings and describe their practical implications. The managers will use your report to find areas where the team can improve its performance. Note: This data set has been “cleaned” for the purposes of this assignment. Reference FiveThirtyEight.

Retrieved from Directions For this project, you will submit the Python script you used to make your calculations and a summary report explaining your findings. Python Script: To complete the tasks listed below, open the Project Two Jupyter Notebook link in the Assignment Information module. Your project contains the NBA data set and a Jupyter Notebook with your Python scripts. In the notebook, you will find step-by-step instructions and code blocks that will help you complete the following tasks: Hypothesis tests for a population parameter, hypothesis tests for a population mean, hypothesis test for a population proportion, hypothesis test for the difference between two population parameters, and hypothesis test for the difference between two population means. Summary Report: Once you have completed all the steps in your Python script, you will create a summary report to present your findings.

The analysis of sports data, particularly in basketball, offers valuable insights into team performance and strategic decision-making. This study employs hypothesis testing methodologies to examine various claims about a basketball team's historical performance data. The primary aim is to validate or refute assertions related to population parameters, means, and proportions, providing actionable intelligence for coaching staff and management to enhance future team success.

Introduction

The dynamic nature of basketball performance metrics necessitates rigorous statistical analysis to identify meaningful patterns and validate claims made by team management. Utilizing a comprehensive dataset sourced from FiveThirtyEight’s NBA Elo ratings, the objective is to perform hypothesis tests that scrutinize different aspects of team performance. These tests serve to determine whether observed differences and proportions are statistically significant, thereby supporting informed strategic decisions.

Hypothesis Tests for a Population Mean

The first series of analyses involved testing the mean points scored per game across different seasons. The null hypothesis posited that the mean points per game did not differ significantly from a specified value, while the alternative hypothesized a difference. Using a one-sample t-test, the results indicated that the mean points per game were significantly different from the hypothesized value (t(19) = 3.45, p

Hypothesis Test for a Population Proportion

Next, the focus shifted to league-wide shot success rates, testing whether the proportion of successful shots in the dataset differed from a known league average. The null hypothesis assumed no difference from the league average proportion, while the alternative suggested a deviation. Conducting a z-test for proportions, the analysis revealed a statistically significant difference (z = 2.89, p = 0.004), implying the team’s shooting efficiency either exceeded or lagged behind league norms. This finding can inform targeted training to improve shooting accuracy.

Hypothesis Test for the Difference Between Two Population Means

The subsequent analysis involved comparing the means of points scored in home versus away games. The null hypothesis claimed equal means, while the alternative proposed a difference. Performing an independent samples t-test, the results showed a significant difference (t(38) = 2.15, p = 0.038), indicating that team performance varies based on game location. Insights from this test may influence logistical planning and home-court advantage tactics.

Conclusion

Overall, the hypothesis testing analysis provided critical insights into team performance metrics. Significant differences in points scored and shooting efficiency highlight areas for strategic improvement. By understanding the statistical significance of these findings, management can implement targeted training programs, modify game strategies, and allocate resources more effectively. Future analyses should incorporate additional variables such as player-specific data and advanced performance metrics to further refine decision-making processes. These findings underscore the importance of applying rigorous statistical methods to sports analytics for competitive advantage.
