Part C: Making Graph and Data-Based Decisions (60 points)


Paragraphs should be typed and written in complete sentences.  Please use project headings for each section.  Use Times New Roman, 12-pt font and double space.  Cite any resources in APA format. 


This assignment requires you to collect your own data and to use that information to make decisions. This project happens in two parts. Part (due Seminar 4) requires you to identify a topic. Parts 2-5 (due Seminar 5) require you to collect and use the data.


You will need to collect both qualitative and quantitative data.  You must design a survey to collect your data.  Make sure you have at least one qualitative and a least one quantitative variable question included in your survey.  Your instructor must approve your idea and survey before you start collecting data.  You may be able to collect your data in another method (i.e. internet sites) only with instructor approval. Examples and ideas are included on page 3.
