Statistics and data analytics2016/17
The course aims at introducing the fundamentals of descriptive statistics, probability and parametric inferential statistics.
Expected results
Students will be able to carry out basic explorative analyses and inferences on datasets, they will know the main probability distributions and will be able to understand statistical analyses conducted by others; moreover, they will know simple methods for the problem of binary classification, and will be able to evaluate their performances. The students will also acquire the fundamental competences for studying more sophisticated techniques for data analysis and data modeling.
