confidence intervals
Bootstrapping is a statistical procedure that utilizes resampling (with replacement) of a sample to infer properties of a wider population.
Say it with me: An X% confidence interval captures the population parameter in X% of repeated samples.
In the course of our statistical educations, many of us had that line (or some variant of it) crammed, wedged, stuffed, and shoved into our skulls until definitional precision was leaking out of noses and pooling on our upper lips like prop blood.
Or, at least, I felt that way.
