biometrika+Mini-Proposals

I reread Chapter 2 in [|LTT] and it struck me that having you write "articles" about data you collected would be a nice Authentic Learning/Assessment activity. So what follows will be a self published journal of data and analysis of your data you collected.

Here is a repeat of the First Assignment:

Think of two pairs of quantitative variables whose relationship you might be interested in studying. (Remember that a quantitative variable is any characteristic of a person or object that can assume a range of numerical values) Be very specific in describing these variables; identify the observational units as well as the variables.

Your published article will involve creating and performing your own experiment. It must involve measurable quantitative bivariate data with some EXPECTED relationship. You should have at least 30 data pairs (only with permission may you have less). You must MEASURE THE DATA YOURSELF. In other words, you may not get it from a book, the Internet, a printed list, or by asking someone else, etc.

Try NOT to pick a “perfect” scientific relationship. In the past students have done such crazy things as:

• # of pieces of dog food consumed versus time for their pet dog to eat them.

Please do something you are interested in. Of course, since you only have two quantitative variables in this experiment, it will be limited.

You will eventually have to write a full report for the experiment so word process this first step. Write just enough so someone else can clearly understand what you are thinking of doing without having to ask you to explain it:

Due November 14th

• What is the research question? Be very specific about exactly what your are going to measure. What is the case? What are the two variables? • Try to be specific about where and how you are going to measure it (remember the word replicable). Of course this is a short assignment, so do what you can. • State what type of relationship you expect between the variables and why.
