The goal of this (one-year) course is to teach students the basic concepts of probability and statistics, and its applications in psychology. 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 use R, a free software environment for statistical computing and graphics, for some of the homework problems. The weekly 實習課 led by TAs is mainly for teaching R and also for problem solving.
