Course topics include probability, random variables and distributions, expectations and variances, sampling distributions, law of large numbers, central limit theorem, hypothesis testing, analysis of variance, covariance and correlation, and linear regression. We will also touch issues and rationale of power, confidence interval, multiple comparison, and goodness of fit. Some commonly-used tests, such as the chi-square test, t test, F test, and some non-parametric tests, will be introduced. We will also introduce the R software for statistical analysis. There are mandatory weekly 實習課 led by TAs for teaching R and also for problem solving.
