statistics project

Introduction This can be one or two paragraphs, does not need to be long. Introduce your project. What was the subject of your study? What were you trying to learn? Why did you choose this topic? Data Collection Explain in some detail how you collected your data. • How did you ensure random sampling? • What variables are in your set of data? • How much data did you collect? Include at least a portion of the raw data (a page or less). • Say something about your overall experience of collecting the data. Descriptive Statistics Display your data in several forms of charts. Summary statistics can be shown in a table or within a chart. This may take up a few pages of your report. • Show each chart and describe what it shows you about your data. • Be sure to use axis titles, legends, chart titles, or whatever is needed to make your charts easy to understand. • Be sure to select charting tools that are appropriate for the kind of data you have. • Your charts should reflect the variables and categories within your data. The charts should serve as visualizations of the statistical analyses you will show later. Inferential Statistics In this section you perform the test of hypothesis and create a related confidence interval. • State the null and alternative hypotheses. • Give the value of alpha (?) you selected as the risk of Type 1 error. • Show the calculation of the test statistic. • Give the conclusion rejecting or not rejecting the null hypothesis. Along with this conclusion you should state the p-value and alpha level. • Explain the conclusion in terms of your project and data. • Describe for your hypotheses what the Type 1 and Type 2 errors would be and the consequences of each type of error. • Create a confidence interval for the population parameter and interpret the interval in terms of the project. Conclusion This section is a short summary of your findings. • What were the main conclusions your came to in your project? • Aside from what the data showed, what else did you learn about the field of statistics in the course of planning and executing this project? Was it easy, interesting, difficult? Say anything else you want about your experience doing this project.
