Data Session 9: Random Sampling and Estimation

In this session, you will learn how to use results from a random sample to estimate characteristics of an entire population. To predict the accuracy of your estimates, you will investigate the variation in estimates based on repeated random samples from that population. Note 1

In This Session:

Part A:

Random Samples

Part B:

Selecting the Sample

Part C:

Investigating Variation in Estimates

Part D:

The Effect of Sample Size



Learning Objectives

In this session, you will estimate population quantities from a random sample. You will learn how to do the following:


Define an estimate based on sample data


Select a random sample


Describe sample-to-sample variation


Predict the accuracy of an estimate


Assess the effect of sample size on the accuracy of an estimate
