Course description
/objective:

The purpose of this course is to introduce important concepts of statistics, such as sampling, estimation, hypothesis testing and regression analysis. An introduction of analysis of variance (ANOVA) and time-series analysis will also be discussed. Students are expected to learn the methods of inferential statistics, the logics of hypothesis testing and regression analysis. The topics covered in this class will be important building blocks especially for the econometrics classes students will take in the third year. Make sure to understand each concept clearly.
