### 100-Level Statistics Courses

STATS 100: Introduction to Statistics, Probability and Mathematical Modeling

Statistical reasoning for learning from observations; continuous and discrete mathematical approaches for modeling a variety of scientific phenomena. Emphasis is on the interplay between data, statistical and mathematical principles and the human activity of modeling, as opposed to specific methods or theories. (4 credits)

No credit granted to those who have completed or are enrolled in SOC 210, STATS 280, 250, 400, 405 or 412, IOE 265, or ECON 404 or 405.

STATS 125: Statistics, Games and Coincidences

Different topics in statistics, probability and game theory will be discussed in the context of various current events and media stories. The seminar will emphasize the understanding of the complexity of the data analysis involved.

(First Year Seminar) (3 Credits)

STATS 150: Making Sense of Data

Can you really make statistics say anything you want? Yes and no. Some common statistical comparisons are susceptible to coercion, but there are others that can be trusted to tell the truth. We explore their differences, using the examples from the social and medical sciences and cutting-edge computing and graphical techniques. (3 Credits)

May not be repeated for credit. No credit granted to those who have completed or are enrolled in SOC 210, IOE 265, STATS 250(350), 280, 400, 412, or ECON 404, ECON 405.

STATS 180: AP Statistics

Credit is assigned for a score of 4 or 5 on the AP Statistics test. Those with STATS 180 credit may proceed to STATS 280 (while keeping full credit for STATS 180) or may take STATS 250, in which case they receive full credit for STATS 250 but lose their credit for STATS 180.

Students with STATS 180 may also bypass both STATS 250 and STATS 280 and take any Statistics class for which STATS 250 is prerequisite. It is an individual choice which Statistics course to take following AP Statistics, but here is some guidance.

Those who took AP Statistics several years ago, or do not feel ready to proceed to a more advanced course, are encouraged to take STATS 250. Otherwise, STATS 280 may be a suitable choice, particularly for those considering a Statistics major. Those considering a Statistics or Applied Statistics minor can take either STATS 280 or STATS 401.
