Find the z-score of a particular measurement given the mean and standard deviation. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

An online course on the fundamentals of statistics including video lessons in Mean, Median, and Mode; Weighted Averages; Quartiles and Boxplots; Range and Standard Deviation; Normal Distribution; Z-scores; Intro to Inferential...

Provides lengthy explanations of the measures of central tendencies - mean, mode, and median - and the measures of variability - range, variance, standard deviation - are given here. Graphs of interesting "side items" are presented as...

Should Fred receive a certificate for scoring in the top 2.5% of a statewide standardized test? Given the test scores for a large population and the mean and standard deviation, young scholars will decide if Fred's score is good enough....

Students are tasked with solving a common issue for automobile manufacturers that require the students to use normal distribution as a model for data distribution. They will also use mean and standard deviation to figure out the problem....

Video presentation on the probability of independent events, covering related topics: multiplication rule, random variable, and mean and standard deviation. [28:41]

Change the median and standard deviation of an automatically generated normal distribution to create a skewed distribution, allowing you to observe properties like what it means for the mean, median, and mode to be different.

This set contains questions about simulating sampling distributions. Students see graphs of simulated distributions enabling them to reach conclusions about mean, shape, and standard deviation.

This section explores the concept of sampling variability in the sample proportion. It will address the effect on the mean and standard deviation of a sample distribution as the sampling size changes.

Enter data and view the mean, median, variance, and standard deviation of the data set.

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...

Compute the expected value given a set of outcomes, probabilities, and payoffs. Students receive immediate feedback and have the opportunity to try questions repeatedly or receive hints.

Dozens of statistical terms are defined and illustrated in this glossary.

Use this Common Core Math Standards Browser to search specific math concepts and their corresponding standards. This page focuses on Using Probability to Make Decisions. Click on the links to find lessons, activities, videos, and study...

Presents a problem that is similar to what might be on an AP Statistics exam. Walks students through each step for solving it and students input answers to questions along the way.

[Free Registration/Login may be required to access all resource tools.] Understanding the mean and statistical deviations.

A tutorial to understand the three central tendencies and how to find them, as well as the standard deviation of values. Offers a discussion and practice problems.

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

See how Z-scores are related to the Empirical Rule from the standpoint of being a method of evaluating how extreme a particular value is in a given set.

Below are the heights of the players on the University of Maryland women's basketball team for the 2012-2013 season and the heights of the players on the women's field hockey team for the 2012 season. (Accessed at...

Students will determine the mean, median, mode and standard deviation of collected data. They will make a frequency histogram of the grouped data, both on graph paper, and on the TI 83+.

[Free Registration/Login may be required to access all resource tools.] Introduces students to the Central Limit Theorem. Students will learn about the Central Limit Theorem and calculate a sampling distribution using the mean and...

Normal distributions come up time and time again in statistics. A normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls within 1 standard deviation.
