1. Chapter 7: Introduction to Sampling Distributions
Section 1: Sampling Distributions

2. population – entire set of elements or individuals
sample – subset of population

3. parameter – numerical descriptive measure of a population
statistic – numerical descriptive measure of a sample ( , , ) (
, s, s )

4. Binomial Distribution proportion or probability of success
population – p
sample – “p-hat”

5. Statistics are used to make the following inferences about their corresponding parameters:
1. to estimate the value of a
population
2. to formulate a decision about the value of a population parameter

6. Sampling Distribution
probability distribution for a statistic
used to evaluate the reliability of inferences
