This module provides a brief review of quantitative concepts that are frequently used in public health. It has been designed, not as an extensive review of mathematics, but as a very focused summary of quantitative concepts that are useful in public health. Many students will find this refresher unnecessary, but students who have not had any quantitative courses in college may benefit from this review. This module should be mastered prior to matriculation.
After successfully completing this module, the student will be able to:
- Define commonly used mathematical symbols.
- Perform a series of mathematical operations in the correct order.
- Convert among simple fractions, decimal fractions, and percentages.
- Compute percent change.
- Explain the differences between simple ratios, proportions, and rates and give examples of each.
- Simplify and solve basic algebraic problems.
- Explain the relationship between exponential expressions and logarithms.
