STAT 02360 · 3 cr · Advanced (300+)

Probability and Random Variables

Advanced credit and the rigorous layer above Stats I — Praxis probability loves this.

Suggested prep window: 3–4 weeks

Prerequisites to lock first

  • Calc II helpful (integrals for continuous RVs)
  • STAT 02260 Statistics I (you already have this)

A-grade strategy

  • Always draw the sample space / tree / table before formulas.
  • Separate discrete vs continuous recipes clearly in your notebook.
  • Memorize common distributions (Bernoulli, Binomial, Poisson, Uniform, Normal, Exponential).

Tutorials & videos

Watch intuition first, then full lectures, then drill. Links open free resources (YouTube, Khan, MIT OCW, notes).

Self-check (no notes)

If you can do these cold, you are ready to start the Rowan section strong.

  • Compute a conditional probability from a two-way table.
  • Find E[X] and Var(X) for a simple discrete RV.
  • Recognize when Binomial vs Poisson vs Normal is the right model.
