Learn about sampling with and without replacement by randomly drawing marbles from a bag.

Young scholars learn about sampling with and without replacement by simulating marbles being drawn out of a bag. Settings can be altered to explore conditional probability.

Young scholars will use a data set to demonstrate that they know what it means for two variables to be associated. Explanations and solutions are provided.

A guide to support parents as they work with their students in statistics and probability.

This is a resource for many topics in probability and statistics. Click on the topic of your choice for an explanation. The sites you will be linked to are quite extensive. A degree of higher-level math is necessary for understanding...

Students learn about the concept of taking a survey by exploring a tutorial. They can then test their knowledge by taking a ten question assessment that increases in difficulty as they correctly answer questions.

Given a context, create a probability distribution. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Look at the results of different experiments, and determine if they are statistically significant. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Examine public opinion and the various means in which to collect it as well as how the government uses the opinions collected. This resource offers video, readings, web resources, and activities.

In this activity, students investigate how to use random numbers to collect samples and how to randomly assign subjects to experiments to collect data. They also use the CBL system to collect data in real time.
