Learning Outcomes

After completing this course, the student will be able to:

1. Distinguish between categorical and quantitative data.
2. Use correct vocabulary to describe surveys, experiments, and observational studies.
3. Construct appropriate graphical displays of categorical and quantitative data.
4. Compute summary statistics for quantitative data.
5. Perform computations using the normal distribution.
6. Perform computations using probability distributions including the binomial, normal, and t-distribution. May also include the uniform, Poisson, and chi-square distributions.
7. Perform calculations using the Central Limit Theorem.
8. Construct confidence intervals from one- and two-variable data and use them to make inferences about parameters.
9. Make inferences about population parameters using hypothesis tests, from one- and two-variable data.
10. Construct and interpret a linear regression model on bivariate data.
11. Determine if linear correlation is statistically significant using the linear regression test.
