Chapter 6 Introduction to Sampling
We’re going to talk about different ways to sample from a population, but before we do that it might be helpful to review a few terms we learned earlier in the course:
A
population represents all possible subjects of interest.
A
parameter is a value that describes a characteristic of a population.
A
sample is a subset of a population
A
statistic is a value calculated from a sample and it estimates the value of a parameter.
