It is not very mathematical, but you need to be comfortable with math at the level of high-school algebra. Taught by Professor Philip B. Stark, this course covers topics: reasoning and fallacies, descriptive statistics, association, correlation, regression, elements of probability, set theory, propositional logic, chance variability, random variables, expectation, standard error, sampling, hypothesis tests, confidence intervals, experiments and observational studies, as well as common techniques of presenting data in misleading ways.
