Change in direction for the class

I realized after the last class (on factor analysis) that I was doing the class a disservice. The mathematical underpinnings of measures of association, regression, factor analysis etc are not what you guys need most. There are kind of three ways of teaching a course like this. 

Approach 1. In-depth examination of research methods from a formal, mathematical perspective. So formal measurement theory, vectors and matrices, how correlation really works, the underlying math of factor analysis, and so on.

Approach 2. In-depth, hands-on workshop on how to use the main techniques of data collection, construction and analysis in the social sciences. Mostly about the software and the actual nuts and bolts.

Approach 3. Survey of the components of a research project. Exposure to key concepts, such as measurement, validity, reliability etc, as well data collection techniques and data analysis techniques. Emphasis on what they are and what they are used for, but not how they work. 

I intended the course to be a combination of Approach 1 and Approach 2.  But now I am going to reorganize things to be about 70% Approach 3, and 30% Approach 2. My sense of aesthetic purity says go 100% Approach 3, but I can't resist showing you some tools you can use to analyze real data. It is too much fun.

Of course, it is hard to let go of the math stuff too. So my approach is going to be "if you don't ask, i won't tell". But I hope you do ask about the mathematical nuts and bolts underneath the techniques, and I will explain.
