Learning outcomes
The aim of the course is to illustrate basic concepts and techniques of statistics.
Special emphasis will be given to practical applications in economics and social sciences. Student will be requested to be able to apply simple statistical techniques and to interpret reports that use statistics and probability.
Course contents
Summarizing data
1. Types of data (measurement and categorical variables); frequency distributions.
2. Mean, median, and mode; range, variance, and standard deviation.
3. Box plots.
4. Hetherogeneity measures.
5. Index numbers. Laspeyres and Paasche price indexes.
6. Bivariate distributions. Dependence concepts and measures.
Elements of probability
7. Basic concepts and definitions. Random variables and the associted probability distributions. Examples of probability models: Bernoulli, binomial and Gaussian distributions. Independence. The central limit theorem.
Statistical inference
8. Introductory remarks; samples and populations; random sample.
9. Parameters and parameter estimates. Desirable properties of estimators. The estimation of the mean and the variance. The estimation of a proportion. Maximum likelihood estimators. Confidence intervals.
10. General theory of testing statistical hypotheses. Hypothesis testing on mean and proportions.
Linear regression
11. The simple linear regression model.
