Ch. 18 Sampling Distribution Models
Objectives
"Our emphasis on models has laid important groundwork. These are sampling distribution models – useful idealized descriptions. Because our emphasis is on the concept of a sampling distribution model rather than on details (after all, we’ll see a number of sampling distribution models before the end of the course), we illustrate the concept with both proportions and means. The principal result is the Central Limit Theorem, which we dub the Fundamental Theorem of Statistics."

Intro to Sampling
This is a great video introducing the idea of sample distributions of proportions and means. Watch the shape and the center as more samples are taken. Notes Through Examples: This video works through example problems while teaching you the formulas. Watch how the formulas are used to calculate the probability or area under the normal curve. |
