## Math 15: Elementary Statistics

At College of the Redwoods, Math 15 is the course number for our Elementary Statistics course. Elementary Statistics is a transfer-level math course needed for preparation for many natural and social science majors.

**Prerequisites**: Grade of C or better in Math 120 (Intermediate Algebra) or equivalent, or an appropriate score on the math placement exam.

**Course Description**: The study of statistical methods as applied to descriptive statistics and inferential statistics. An emphasis on the meaning and use of statistical significance will be central to the course. Students will use frequency distributions, graphs, measures of relative standing, measures of central tendency, measures of variability, correlation, and linear regression to explore descriptive statistics. Students will use the laws of probability and statistical tests (t-tests, chi-square, ANOVA, and regression analysis) to make decisions via hypothesis testing and estimate parameters using confidence intervals.
