1.Introduction: population vs sample 2.Data characteristics

Descriptive statistics 1.mean, standard deviation2.median, Q1, Q33.coefficient of variation4 statistical software: SPSS

Commonly used distributions:1.Normal distribution2.Binomial distribution (for binary data)2.Excel3.Sampling distribution of sample mean4. LLN, CLT

Point estimation for the population mean (I):1. Point estimation and interval estimation 2. One sample inference: mean3. t-distribution

Point estimation (II):Two independent samples: difference in means and proportions
