Project 2

Scenario

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.

Introduction: Problem Statement

Discuss the statement of the problem in terms of the statistical analyses that are being performed. In your response, you should address the following questions:

· What is the problem you are going to solve?

· What data set are you using?

· What statistical methods will you be using to do the analysis for this project?

Answer the questions in a paragraph response. Remove all questions and this note before submitting! Do not include Python code in your report.

Introduction: Your Team and the Assigned Team

In the Python script, you picked the same team and years that you picked for Project One. The assigned team and its range of years will be the same as in Project One as well.

See Steps 1 and 2 in the Python script to address the following items in the table below:

· What team did you pick and what years were picked to do the analysis?

· What team and range of years were you assigned for the comparative study? (Hint: this is called the assigned team in the Python script.) Present this information in a formatted table as shown below.

Table 1. Information on the Teams

	Name of Team	Years Picked
1. Yours	Team (e.g. Knicks)	XXXX-YYYY (e.g. 2013 - 2015)
2. Assigned	Team (e.g. Bulls)	XXXX-YYYY (e.g. 1996- 1998)

Answer the questions in a paragraph response. Remove all questions and this note (but not the table) before submitting! Do not include Python code in your report.

Hypothesis Test for the Population Mean (I)

Suppose a relative skill level of 1342 represents a critically low skill level in the league. The management of your team has hypothesized that the average relative skill level of your team is greater than 1342. You tested this claim using a 5% level of significance. For this test, you assumed that the population standard deviation for relative skill level is unknown. Explain the steps you took to test this problem and interpret your results.

See Step 3 in the Python script to address the following items:

· In general, how is hypothesis testing used to test claims about a population mean?

· Summarize all important steps of the hypothesis test. This includes:

a. Null Hypothesis (statistical notation and its description in words)

b. Alternative Hypothesis (statistical notation and its description in words)

c. Level of Significance

d. Report the Test Statistic and the P-value in a formatted table as shown below:
