MATH 115 - Statistics

Course Description

  • Prerequisite: "C" or higher in MATH 25 OR placement in MATH 115
  • Recommended Prep: Placement in ENG 22/60

A basic introduction to topics in statistics, with a brief look at probability. Emphasis on applications to physical and social sciences.

Student Learning Outcomes

Upon successful completion of Math 115, the student will be able to:

  • Articulate and interpret various descriptive statistics, such as mean, median, mode, range, variance, and standard deviation
  • Organize, draw, and interpret various graphs such as frequency histograms, bar graphs, and pie charts
  • Solve probability problems involving the concepts of independent events, mutually exclusive events and conditional probability
  • Use the binomial and normal probability distributions to calculate the mean and standard deviation
  • Calculate probabilities involving normal random variables
  • Determine and interpret (for large samples) confidence interval estimates of population means
  • Perform hypothesis testing
  • Draw a scatter diagram, determine and draw the corresponding regression line, and calculate and interpret the corresponding correlation coefficient for a set of paired data.

In general, the course will provide the student with a basic working knowledge of the methods of statistical inference, and how these methods can be applied to "real life" situations. In particular, the formation and testing hypotheses is emphasized.
