Understanding how to describe the distribution of continuous data.

). A is a subset collected from the population, yielding observed statistics (e.g., sample mean, X̄cap X bar The Law of Large Numbers (LLN)

So the next time you sit down for a mathematical statistics lecture, come curious, stay active, and remember: every confidence interval you will ever compute, every A/B test you will run, and every machine learning model you will tune owes a debt to these 60 minutes of disciplined reasoning.
