# Ch 4: Mathematics in Science

Learn more about mathematical processes and how they directly relate to science. These video lessons and quizzes teach you about the concepts of probability, proportion and unit rate to refresh your knowledge on the topic.

## Mathematics in Science - Chapter Summary

In this chapter, you'll learn about one of the most useful methods scientists use to predict outcomes--the unit rate. You'll be introduced to the concept of inverse variation and learn what makes something inversely proportional. You'll also learn about probability, as well as ratios and proportions.

Other lessons in this chapter cover the measures of central tendency, including median, mean, range and mode. You'll also learn about how fractions and percent are related to one another. After you've reviewed this chapter, you should be able to:

• Find the rate of change to predict outcomes
• Write algebraic equations for inverse variations
• Apply ratios and proportions to real-life situations
• Calculate the mean, median, mode and range of a data set
• Turn a fraction into a percent and a percent into a fraction
• Solve percentage word problems
