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...

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...

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.
