Week 8 ASSIGNMENT AND EXPLANATION

For this project, you will perform a statistical study in the field of health using a data set provided to you. You will discuss your work in some of the weekly Discussion Forums, so you will need to keep up with this project for the remainder of the term. You will submit your project information/results/calculations in PowerPoint and Excel spreadsheet formats in Week 08.

For your project:

Choose a data set for your course project from among the ones posted in the Course Materials folder. You will note that some of the data sets have continuous data while some have dichotomous data.

Decide on assumptions for your data. For example, when applicable, you can assume that the data is for American teenagers, ages 13 to 16.

Depending on the data set that you choose, you may do a one or two-sample test. If doing a one sample test, look through recent articles on the Internet for someone else's claim about the population parameter that you will support or refute.

Formulate your informal hypothesis (i.e. what you think is true). For example: "The average number of hours that American teenagers (ages 13 to 16) sleep is less than that for the general population." State why you think your hypothesis is true. Write your formal null and alternative hypothesis.

Using the sampling technique assigned to your data set, describe how data may have been gathered using this technique.

Create a frequency distribution table for your sample(s) in Excel. Create a histogram or bar chart, as applicable.

Calculate sample mean, median, mode and standard deviation or sample proportion, as applicable, for your sample(s) in Excel.

Create a confidence interval for your sample(s).

Test your hypothesis.

Formulate a conclusion based on your results. State formally and informally.

Show all your calculations and back-up work in an Excel file. Make sure that the Excel file is organized, complete and clear. Do not forget to put the data set you have selected in the first worksheet of your Excel file.

Assemble all of your results and comments in a PowerPoint presentation that includes the following:

Introduction - What you are studying and why?

Hypothesis - State informally and formally.

Method - Using the sampling technique assigned to your data set, describe how the data may have been collected?

Results – Graph(s), table(s), descriptive statistics, confidence interval(s), steps for hypothesis-testing - insert graphs and tables from Excel

Conclusions - Reject or fail to reject your null hypothesis, state formally and informally.

Comments - Are there things that could have been improved? What are the possible errors made in this study? What follow-up study might shed more light on your chosen subject?
