Description

Modeling Randomness: Binomial and Normal Distributions is Unit 5 of Statistics and Data Science: An Introduction to Statistical Reasoning (Part 2) (Grade 12), the Letters & Devotion Math course, complete in one printable PDF: 10 lessons, the unit check-up and the answer key, 84 pages.

• The four defining conditions of a binomial setting
• The binomial probability formula P(X=k) = C(n,k)p^k(1-p)^(n-k)
• Mean and standard deviation of a binomial distribution
• The emergence of normal shape from repeated independent binomial trials (informal Central Limit intuition)
• The 68-95-99.7 empirical rule for the normal distribution
• The z-score formula z = (x – μ)/σ applied under a continuous normal model
• Cumulative normal proportions via table lookup and NORM.DIST/NORM.INV
• Appropriateness of the normal model as a fit for a real distribution
• Discrimination between binomial-appropriate, normal-appropriate, and neither-appropriate scenarios
• The applied use and limits of the normal model as a decision tool

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
