Course-level Learning Objectives (CLOs)
Upon successful completion of this course, students will be able to:

1. Distinguish between quantitative and categorical data.
2. Display categorical data using frequency tables and two-way tables.
3. Construct appropriate graphical displays of quantitative and categorical data by hand and using technology.
4. Compute appropriate summary statistics for quantitative variables.
5. Perform computations using the Normal model.
6. Construct and interpret scatterplots of bivariate quantitative data.
7. When appropriate, compute the correlation of two quantitative variables.
8. When appropriate, construct and interpret a linear regression model on two quantitative variables.
9. Interpret a residual plot.
10. Use random numbers to perform a simulation.
11. Appropriately use terms related to sample surveys, experiments and observational studies.
12. Perform basic probability computations.
13. Compute the expected value and standard deviation of a random variable.
14. Perform computations with probability models, including the binomial model.
15. When appropriate, construct and interpret a confidence interval and perform a hypothesis test in situations involving: a. one proportion; b. two proportions; c. one mean; d. two means.
16. When appropriate, use chi-square methods to perform: a. goodness-of-fit tests; b. tests of homogeneity; c. tests of independence.
