Students graph normal distributions, shade desired areas, and find related probabilities. They graph Normal probability scatter plots to check the normal (linear) shape of a data distribution.

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 exponential, normal, and beta distributions. The tutorial investigates the statistics concepts through class notes and examples. Review exercises and a normal probability calculator are included.

The history of the normal curve and its use in statistics is presented. An Applet is provided for the user to adjust the left and right edges of the probability and see the effect on the area under the curve.

In this activity students will contribute a set of random points to a graph of a circle of radius 1 inscribed in a square. They will estimate the area of the circle using geometric probability.

The learning tool calculates the probability of a binomial distribution.

Enter the world of Poisson Distributions. A brief background is given on the properties and applications of the concept. Examples are presented for calculating probabilities, mean and variance for situations that fit the conditions of...

Simulations that show the concepts of probability distribution and the behavior of electrons that will help students understanding of quantum mechanics. Students will learn about electrons movement when they are in an excited state. At...

Formulas and properties of the normal distribution are presented, including details on the normal random variable and the standard normal distribution. Several real world examples are also included with detailed solutions.

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

Using the random function with probability and non-uniform distributions in code.

Practice explaining the shapes of data distributions. Some distributions are symmetrical, perfectly balanced on the left and right. Other distributions are unbalanced. We say they are "askewed" and have "tails." Students receive...

Practice comparing distributions that are presented in dot plots, histograms, and box plots. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Take a look at two different data distributions and draw some comparisons. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Try these practice problems comparing distributions.

Practice comparing distributions of data in different forms of graphical representation.

Simulate the binomial distribution of a Galton board as a ball is dropped into the device. Investigate the probability of the ball going to the right or to the left with each bounce off a peg.

Students will find solutions for a series of questions based on the assumption that SAT mathematics scores for a particular year are approximately normally distributed with a mean of 510 and a standard deviation of 100. Explanation and...

[Free Registration/Login may be required to access all resource tools.] Use percentages associated with normal distributions to solve problems.

Mini lessons are provided for learning concepts in the world of probability and statistics. Topics include counting and probability, permutations, combinations, independent and dependent events, and distributions. Links to online...

This site provides an overview of sampling distribution and associated terms.

The Applet illustrates how to use the old-fashioned tables of normal probabilities and areas under the normal distribution cureve to arrive at corresponding graphs of the areas. A good resource for the topic.

Students learn about probability density functions and uniform distributions. The tutorial investigates the statistics concepts through class notes and examples. Review exercises are included.

In this lesson, young scholars compare strategies by evaluating the associated probabilities of success. Additionally, problems are included where students are asked whether the result of a probability experiment provides sufficient...
