Project Overview 1. Choose a research question: a) that can be addressed using a t-test b) for which you can collect data to analyze 2. Devise a plan to collect your data 3. Submit a project plan form to the instructor and obtain approval 4. Once your research question and data collection plan are approved, carry out your research: a) Collect data b) Conduct t-test analysis, using guidelines below c) Write your results in a report, using the outline given below 5. Turn in your written report using the link in Module 9 of the course Blackboard site. Data Collection Options: The following are suggestions on where you can collect data. 1. Reliable/reputable websites (e.g., sponsored by the census bureau, professional sports leagues, universities, real estate agencies, car manufacturers, consumer groups, financial institutions, well- known product manufacturers, restaurants/fast food companies, weather tracking agencies, county/city/state/federal government organizations, etc.) 2. Visit to one or more locations where item(s) you are researching can be found (e.g., stores to write down prices, rivers to count turtles, car dealers to write down data about cars, etc.) 3. Other resource by permission (if you have an idea, ask your instructor). Important Note: ERAU and all other universities have strict policies and approval procedures for any research projects that involve collecting data from human subjects. There is not time in this course for you to go through that approval process. Therefore, your project in this course cannot involve directly collecting data from human subjects. This includes conducting surveys. Project Design There are 3 project design options for the t-test project, listed below. To see components and examples for each type of project design, consult the t-test Project Examples Word document or the t-test Project Resources PowerPoint file. A. The 1-sample t-test (Sample size must be at least n = 40.) B. The matched pairs t-test (Sample size must be at least n = 40.) C. The 2-sample t-test (independent samples) (Sample size must be at least n = 50. You may split this across your two samples; for example, you may have two independent samples of size 25, or one of 27 and another of 23, etc. Although your independent samples are not required to be identical in size, it is better if the sample sizes are similar.)
