Use statistical methods to make a formal inference
Internal 4 credits Bootstrap Confidence interval Inference PPDACThe internal where you take two samples, build a bootstrap confidence interval for the difference between their medians, and make a formal inference back to the populations. The marks are in the reasoning, not the button-pressing. You have to say what the interval means and how confident you can be.
Practice
Recall it first, then use it — testing yourself builds the memory, where rereading the notes above only feels easier.
Recall and application shuffled together — you have to work out what each item wants before you can answer it, which is the part the exam actually tests. Both kinds feed the same spacing schedule, so anything you miss comes back sooner.
Say the answer out loud before flipping — that attempt is where the learning happens, even when you get it wrong.
