# Statistics Courses

### 100-Level Statistics Courses

Statistics 100: Introduction to Statistical Reasoning

Provides an overview of the field of statistics, including methods of summarizing and analyzing data, statistical reasoning for learning from observations (experimental or sample), and techniques for dealing with uncertainties in drawing conclusions from collected data. Emphasis is on presenting underlying concepts rather than covering a variety of different methodologies.

No credit to those who have completed or are enrolled in SOC 210, STATS 250/350, 400, 412, IOE 265, ECON 404 or 405 or ENVIRON/NRE 438.

Statistics 125: Games, Gambling and Coincidences

Emphasizes problem solving and modeling related to games, gambling and coincidences, touching on many fundamental ideas in discrete probability, finite Markov chains, dynamic programming and game theory. (First Year Seminar) (3 Credits)

Statistics 150: Making Sense of Data

The course establishes techniques for determining whether relationships between variables, particularly intervention and outcome variable, exist in the sense that the appearance of an association can't be explained by chance. The course formalizes and extends the set of phenomena that can be numerically represented in a way as to permit these modes of analysis. This is done in the interest of making predictions and judgments, particularly about what hypotheses are and are not supported by a set of data and to what extent the data support them. It introduces general perspectives from the field of Statistics to a broad audience of lower-division students. 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 examples from the social and medical sciences and cutting-edge computing and graphical techniques. (First Year Seminar)(3 Credits)

May not be repeated for credit. No credit to those who have completed or are enrolled in SOC 210, IOE 265, STATS 250/350, 400, 412, ECON 404, 405, or ENVIRON/NRE 438

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.
