Distribution of sample means
What you need to know
Understand the principle that a collection of calculated sample means is distributed far more closely around a central value than individual random values drawn from the exact same population.
Apply this principle conceptually, understanding, for example, that the distribution of mean heights calculated across multiple school classes shows noticeably less variation than the overall distribution of every single student's height.
