Statistically, practicing this packet completely helps young mathematicians do well on the test. The packet is adaptable to many grade levels as it includes basic probability and goes up to data analysis with mean, median, and...

Experiment with chocolate coating on cookies! What a delightful way to learn about food processing and chemical engineering. Throughout this activity, groups collect measurements and make calculations. They conclude by writing...

The key is in the leaves. Pupils enter data to create a stem-and-leaf plot. The resource then displays the plot and calculates the mean, median, and mode of the data. Using the plot and the calculated measures of spread, learners analyze...

Slide the class into a skewed view. Learners alter the location of the median relative to the mean of a normal curve to create a skew distribution. They compare the curve to a histogram distribution with the same skewness. 

Build upon and stack up data to get the complete picture. Using the applet, pupils build bar graphs. As the bar graph builds, the interactive graphically displays the mean, median, and mode. Learners finish by exploring the changes in...

Take a look at data from a statistical lens. An interactive allows pupils to enter data set, labeling the data including the units used. Manipulating the applet, learners select the statistics to calculate that include total, mean,...

What information can come from a box? Learners choose a data set to display as a box plot and decide whether to include the median in the calculation of the quartiles, show the outliers, and change the scale. To finish the lesson,...

Adjust the overlap to compare probabilities. Using sliders, learners adjust the shape of two Gaussian curves. The interactive calculates the area of the left tail for one curve and the right tail for the other. Pupils set the interactive...

Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared...

Happy Pi Day! This collection of games, experiments, and activities leads participants through an exploration of the many aspects and attributes of that mysterious quantity, pi. Activities range from using statistical...

What happens when your teachers get tired of grading tests and want to use games of chance to determine your grade? How would you decide which game they should play? Learn how to use expected value and standard notation to compare two...

Here is an activity that is intended to highlight a very important issue about precision in reporting and understanding statements in a realistic scientific context. Discuss different ways of reporting the half life of Carbon 14...

[Free Registration/Login may be required to access all resource tools.] Learn about the spread of a normal distribution.

A series of step-by-step worked problems demonstrating how to take a set of data and produce the variance and standard. Hints are provided along the way and the final measures are shown for the user to check.

Explore what the standard deviation is as it relates to the graph of a normal distribution curve.

This site looks at measures of central tendency and dispersion. Discussed are topics such as standard deviation, mean, median, and mode.

The learning tool calculates the probability of a normal distribution.

The resource consists of a normal distribution table.

A demonstration of how to find the standard deviation of a set of data. Several examples and a practice test are offered.
