Not sure about my data analysis!
Mood:  quizzical
Now Playing: Time Marches on (Tracey Lawrence)
Topic: Data Analysis
I'm looking at my analysis of my data for my LP section. So, what I did, I got Biglan (1973) paper (both of them) and decided to categorized my disciplines according to his methodology that is into hard vs soft; pure vs applied; and life systems vs non-life system. Well, I had some problems in decided which category the disciplines fitted into. For example computer science I felt it should be hard, applied and non-life system. But is computer science considered a pure or applied subject. I wasn't certain about that. Anyway, he had some categories of disciplines in a table so follow that to some extent. What I did too, was that I went to the course websites and see what it is about and what department they were in to fit it in better if I was unsure - such as things that had built and natural environments (just to tell you - I decided those were life systems).

Well, after I did ... decided to look at how the responses were distributed for the coverage and delivery for formulation, solution and sensitivity analysis. Well, I decided to do ANOVAs but something just wasn't going so right with it - because you know this is ordinal and nominal data rather than continuous. So, looked at a bit how to do analysis with that - at first tried some loglinear analysis - wasn't sure what results I got ... well, finally decided to do logistic regression - which seems to be the way to go. I'm doing ordinal logistic regression using the PLUM module in SPSS and it seems to be working out to some extent ... except I've discovered one problem with my logic ... my ordinal variables (i.e. my responses to delivery and formulation) may not be truly ordinal since I have the 'not sure' variable at '5' ... so, I was wondering what to do with that!

Well ... I thought maybe I should make it a missing variable (I've given the value of 999 for my missing variables) - well, I am seriously considering doing that - well, I meet John tomorrow so we'll see what he says.
