Statistics

Sampling and Experimentation

This unit addresses issues related to choosing a sample, including comparing a random sample to other sampling methods and investigating the variability inherent in a random sample. The activities involve comparing samples obtained from a block design to those using a random sample, explore why some blocking designs are more effective than others, and consider different stratification designs.

Title Type

Random Samples

Compare the results of the three estimation methods to show that random samples of rectangles provide estimates that, on average, are closer to the true population mean than the other two methods.
