Statistics Research Project Instructions

MATH 201/BUS 230

On April 4, 2017, Jordan Friedman wrote an article for US News and World Report. He provided the following data about the “average” online learner (retrieved from https://www.usnews.com/higher-education/online-education/articles/2017-04-04/us-news-data-the-average-online-bachelors-student):

You will investigate two of these claims over the course of this term, using your class as a sample. Each week different elements of the project will be submitted and graded by your instructor. Based on your calculations and the feedback from your instructor, you will submit a final write up in week 7 of all your findings.

Points and Due Dates (submissions are due at 11:59pm ET Monday at the end of the indicated week):

Project Part	Due Date	Points
Part 1 – Data Collection (Week 1)	Week 1	10
Part 2 – Descriptive Statistics (Week 3)	Week 3	25
Part 3 – Confidence Intervals (Week 5)	Week 5	25
Part 4 – Hypothesis Testing (Week 6)	Week 6	25
Part 5 – Final Report (Week 7)	Week 7	75

A note on ethics of research in our class: As in any research study, it is important to protect the confidentiality of those who respond to a survey. For this reason, no names of survey respondents will be used, no data will be made public, and no findings will be published outside of our classroom. As this is a student class project where the student investigator gathers or analyzes information in a systematic manner primarily for the learning experience, it is not intended to contribute to generalizable knowledge and is not to be presented outside the class in which the research is being done nor published/disseminated (including publication on the Internet) in any way, nor presented, nor archived, nor compiled with similar research for later publishing or presentation.

(25 points) Part 4 – Hypothesis Testing (Week 6): Based on your sample, you will conduct a hypothesis test with to test two of the claims of the above article.

Using the same excel sheet as last week, answer the following in the “week 6” tab :

· Claim: the average age of online students is 32 years old. Can you prove it is not?

· What is the null hypothesis?

· What is the alternative hypothesis?

· What distribution should be used?

· What is the test statistic?

· What is the p-value?

· What is the conclusion?

· How do we interpret the results, in context of our study?

· Claim: the proportion of males in online classes is 35%. Can you prove it is not?
