Statistics & Probability
IB Topic 4, complete: sampling and bias, data presentation, centre and spread, correlation and both regression lines, the language of probability, combined events with Venn and tree diagrams, discrete random variables, the binomial and normal distributions, formal conditional probability, and z-values — SL 4.1 to 4.12, taught to markscheme standard.
Builds on
SL 1.9's binomial coefficients power the binomial distribution; SL 2.10's equation craft returns in expected-value and unknown-parameter problems.
