| STATISTICAL METHODS FOR SOCIAL RESEARCH (L40)
(objectives)
This course presents the student with some of the basic concepts of descriptive statistics. Discusses the problems of summary statistical information (graphics and analytical) concerning a single character found in a population, focusing on the properties of the arithmetic mean and variability indexes.

This course presents the student with some of the basic concepts of inferential statistic. It discusses the main sampling techniques, the probability theory, the estimation theory and the significativity tests. Among the statistical models, the regression linear model and the analysis of varianza are considered.

- Explanatory statistic.
- Sampling theory: population and sample definition. Probabilistic samplings: random sampling with and without reimission. Stratified sampling. Cluster sampling. Non probabilistic sampling.
- Probability theory. Discrete and continuous random variables. Bernoulli and normal distributions.
- Statistical inference: the estimation. Point and interval estimation. Confidence interval for the proportion. Confidence interval for the mean. Sampling size.
