Can you use data from the 2008 Beijing Olympics medal tables to decide which country has the most naturally athletic population? This data-handling activity encourages mathematical investigation and discussion and is designed to be...

Explore the bell-shaped curve and how to calculate a z score. Additional links provided to further knowledge on outliers.

This resource accepts contributions from younger children, up through age 13. This page explains the process to follow when submitting contributions. Also at this site students will find a link to a sample issue.

Work samples, phenomena, assessment templates, and videos that directly address standard 3-ESS2-2: world climates.

Interactive review problems are offered to practice the concepts of random variables and statistics. Topics covered include, Bernoulli trials, normal and binomial distributions, Chebyshev's rule, and the like.

This set contains questions regarding the Central Limit Theorem. The student sees that, as the size n increases, the shape of the sampling distribution gradually approaches a normal curve, and its population standard deviation decreases.

The concept of random variables comes to life with this Applet used to roll one, two, six, or nine dice. The user selects the number of rolls to be completed, and the program quickly counts and graphs the results.

This interactive lesson begins with the basics and carries through to methods of data analysis, all interactively. Supporting material is excellent.

This is a comprehensive online text about statistics which covers all the basic concepts.

A sample problem on creating intervals for a frequency distribution. The example is worked out and explained along the way.

A random sample of 100 students from a specific high school resulted in 45% of them favoring a plan to implement block scheduling. Is it plausible that a majority of the students in the school actually favor the block schedule? Students...

This comprehensive study guide contains 897 fully solved probability and statistics problems with explanations. Topic covered includes basic probability, sampling theory, regression, and more.

In this activity, students use simulation to justify the concept of the Law of Large Numbers. They understand that as the sample size increases, the relative frequency of which an event occurs approaches the probability of that event...

Visual representations of population distribution by age and sex for any country.

This PDF lesson plan provides students with an understanding of the importance of editing and proofreading at the AP level. The teacher distributes various examples of student work and asks the students to read and comment on the writing...

The list editor provides a means for viewing, editing, and working with data lists. Students can explore distributions, tests, intervals, multiple regression, random sampling, goodness of fit and inferential statistics.

This lesson focuses on the organization of an ecosystem. The feeding relationships between organisms in an ecosystem can be seen in food chains. Sampling allows us to measure the abundance and distribution of these species. It provides...

The task is intended to address standards regarding sample space, independence, probability distributions and permutations/combinations. Aligns with S-CP.A.1.

Definitions of the basic concepts in statistics. Great for review and discussion or for introduction into topics.

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...

A sample problem is provided to help you create a histogram using a frequency distribution chart. Sample charts and formulas are provided to help explain how to find the area of the rectangles in the histogram and how to interpret what...

Almost nothing is known of the ginkgo-toothed beaked whale. Nothing about its behavior or feeding habits has been reported, and its geographical distribution is estimated from a very small sample. Learn more about the Mesoplodon...
