8.4. Chapter Exercise#
Apply the key ideas from this chapter in the connected task below. Work in your own notebook or local project. Keep your implementation, reasoning, and verification results together.
8.4.1. Connect distributions and sampling#
Use a real numeric variable already supplied in the book to describe center, spread, shape, and unusual observations with numbers and a chart.
Specify a simple probability model taught here and simulate repeated samples using a fixed seed, clearly labeling the simulation and its assumptions.
Compare the distribution of observations with the sampling distribution of a statistic at two sample sizes. Explain standard error and why more simulation runs differ from collecting a larger sample.
