Episode notes
Awe On A Bangkok Tarmac
- Patrick describes standing on a Bangkok tarmac at midnight and being awed by the size of a 747.
- He uses this to compare the surprising success of complex systems like airplanes to the bootstrap idea.
Sampling Distributions Explained
- Sampling distributions describe variability of statistics across repeated samples and define standard errors.
- Intro stat uses population theory to estimate standard errors without repeated sampling.
How The Bootstrap Emulates Resampling
- Bootstrapping emulates repeated sampling by resampling with replacement from the observed sample.
- Replacement creates duplicates and approximates drawing from the population when the sample is representative.
