A scenario is presented for chemistry techs to address. Using titration techniques, they must analyze hydrogen peroxide solution samples. They evaluate accuracy and precision in the process. They also gain experience consulting the MSDS...

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. 

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,...

Does the size of the bin matter? The resource allows pupils to explore the relationship between the normal curve and histograms. Learners view histograms compared to a normal curve with a set standard deviation. Using the interactive,...

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...

In this statistics and probability worksheet, young statisticians solve and complete 13 different problems related to probability, percentages, and normal distributions. They consider data models, assumptions about the models, and find...

Students explore about propagation of error in calculations using experimental data. They develop their weighing and pipetting techniques. Students explore the following terms: Standard deviation and relative standard deviatin. They...

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...

In this statistics worksheet, students solve and complete 10 different types of problems. First, they determine the probability of various actions described. Then, students describe an appropriate model for the number described and...

In this standard deviation worksheet, students solve and complete 10 different types of problems. First, they determine the number of standard deviations an item was from its mean. Then, students draw a model of what this would look...

Students explain and learn the practical application of standard deviation. They compare cities in the U.S. and discover whether cities closer to the ocean have more consistent temperatures. Useful resources are given.

Students explore the concepts of mean and variance. They observe properties of materials to their basic atomic or molecular structure. Students use spreadsheet software to record, tabulate and analyze collected information.

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

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

A series of explanations of statistics terms based on the statistics from a dice game.

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

The learning tool displays data in the form of a histogram. The tool also shows descriptive statistics and probability distributions. Examples of data are included.

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