Final Homework/Exercise

I collected the data from a class like this one. It is a small data set consisting of 27 subjects and six variables. Your assignment is to make some sense of the data. Use the procedures that you have learned over the course of the semester where appropriate (e.g., Minitab). For example, in the broadest sense, we talked about both descriptive and inferential statistics. Thus, be sure to describe the data as well as perform various inferential tests.

It has often been noted that in order to adequately describe a set of data, we must talk about three aspects of it (i.e., shape, central tendency, & variability). Thus, you may wish to include tables and or graphs as part of this assignment. When it comes to performing statistical tests, you may find this table helpful in deciding which test/procedure is appropriate for the data involved. However, do not limit yourself to a particular procedure. An important goal of this assignment is to show what you have learned in terms of the "big picture".

Each student should do the assignment individually. The summary of sense you have made of the data should place heavy emphasis on what the analysis means in terms of the variables involved. It should be typed, at least 1-2 pages, and double spaced (with 1 inch margins). Furthermore, use a 12 point font. In addition, create a title page as described here. Note that there is an MS word template for this kind of thing here. Please append the Minitab output, as well as any tables or graphs.

I will use this assignment to gain my final impression of your performance in this course.
