Statistical Methods Crash Course Wanted
January 26, 2010 6:24 PM Subscribe
I need a quick course in statistical methods - Chi squared, Student's t-test, Kruskal-Wallis, etc. I have a research project coming up this Spring and I am sorely lacking in these specifics. Any book or website suggestions appreciated. More about the project inside...

I will be analyzing survey data about physician self-assessment of competency (you know, 1 for not competent, 5 for very competent, type responses) using Stata. We'll be looking for any association with other variables in the survey. Here's the paragraph from the research proposal that has me worried:
Data will be analyzed using both multi-level and longitudinal modeling techniques, as well as factor analysis, Chi-squared test, Student’s t-test, Kruskal-Wallis rank test, univariate correlation coefficients, and logistic regression, as appropriate. All variables that are considered important by the research team will be included in the regression model. Interaction will be formally tested by multiplying the two factors of interest (Factor A * Factor B) and then including this interaction term in logistic regression models. All statistical analyses will be reported using 95% confidence intervals and p-values.
I'm in medical school but don't have any formal statistical courses in my background. Any suggestions for a crash course in statistical methods?>
