I am tutoring students in both intro level statistics (basic probability, combinatorics, binomial distributions, central limit theory, normal distributions, T-tests, P-tests, hypothesis testing) and intermediate statistics (regression, correlation, F-tests, ANOVA, hierarchical clustering, principal component analysis, multivariate analysis). I use statistics everyday in my regular scientific software consulting practice, and I very much like finding the few key conceptual threads that will unravel the field for new students.
