Download these free worksheets to sharpen your skills with statistics and probability. Sheets focus on collecting and organizing data, measures of central tendency (mean, median, mode, and range), and probability.

An extensive collection of links on statistics and probability can be found here! Discussions ranging from the basics of stats through more complex data analysis. Topics are broken down into sections for teachers, students, WebQuest...

An explanation of key terms and vocabulary used in the study of statistics and probability. Includes examples and practice exercises.

This resource explains the different measures of center, variability, etc. that are used to describe the spread of statistical data. Includes examples and practice exercises.

A set of exercises where students must analyze statistcal data and methodology and answer questions about distributions, sampling, results, accuracy, frequency, experimental design, and ethical practices.

The resource from Khan Academy provides practice questions for the Praxis Core Math Test. This section reviews probability and statistics questions connected to the center and spread of data in a collection.

Explore how to interpret a large set of data by dividing it up into smaller portions in order to answer statistical questions.

Create or print a learning exercise to assess students' understanding of identifying populations and samples.

Determines if a statistical study is a sample study, an experiment, or an observational study.

This lesson looks at how to recognize patterns in a data display by examining the shape of a graph, the center, the spread, and unusual features such as outliers. Includes video. [11:16]

When we collect data it's important to know what type of data we're collecting and how to collect it properly.

Provides an introduction to probability. Includes examples, two videos, and links to additional resources, e.g., exercises to try. There are also problems and discussions of them in the Comments section.

Several paragraphs of explanation and graphs are found here to get across the concept of normal scores, z-scores, and the related probability in a simple fashion. This page is part of a collection from the university on basic statistical...

This site provides a general definition of the factors of a statistical experiment.

This site features an online textbook with very in-depth information about multivariable statistics. (NOTE: In the archived version, some images do not appear. However, many of them are multiple-choice questions for students, and if you...

A line plot may not be a useful graph for investigating variation so we must come up with a new representation based on groups of data. Construct a stem and leaf plot from a set of 26 data values.

The object of this project is for students to learn how to find univariate and bivariate statistics for sets of data. Also, the students will be able to determine if two sets of data are linearly correlated and to what degree. The...

Upper level discussion of several of Mendel's experiments and laws.

This site defines probability and has a computer-based random number generator. The site has links to more than 100 probability problems which require some prior statistical knowledge to solve, or they can be great "openers" for teachers...

Find expected value based on empirical probabilities. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Learners play a game by rolling dice and determining the probability of outcomes of colors.

This lesson focuses on the probability and casino games such as Roulette which consists of a wheel with the numbers from 1 to 36 colored in red and black, as well as a green 0. A ball rolls around the outside and randomly lands on one of...

Gain an understanding of combinations and permutations by viewing an example and a video lesson. [1:15]

In the 2008 Beijing Olympics the UK finished 4th in the total medal count. How might we do in 2012, and does the country hosting the Olympics have an edge?
