Suggested background knowledge

To feel comfortable with some topics in this course, students should be familiar with differential and integral calculus.


Mission & Content Summary
MISSION

The course explores techniques for collecting and analyzing data. Concepts of statistical thinking, both descriptive and inferential, are covered. The course introduces the fundamental principles of probability theory and random variables, as a basis for the better understanding of inferential techniques. The focus is on analyzing real data, illustrating some of the methods and concepts with the help of the statistical software R.

CONTENT SUMMARY
  • Combinatorics, probability measures and related elementary properties.
  • Conditional probability and independence.
  • Discrete and continuous random variables. Notable examples. Expected values.
  • Joint distribution, independence, correlation, conditional distributions.
  • Descriptive statistics, population and sampling, frequency tables, graphs, measures of location and spread.
  • Distributions of sampling statistics and related asymptotic distributions.
  • Point and interval parameter estimation.
  • Hypothesis testing.

Intended Learning Outcomes (ILO)
KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • Understand basic concepts of probability required for the use and interpretation of statistical methods.
  • Describe a dataset through adequate graphs, tables and statistics.

  • Identify if the structure of the data allows the application of basic statistical inferential methods.

  • Do inference on the mean of a population (point estimation/ prediction, interval estimation, hypothesis testing).

  • Understand the fundamental logic of estimation and hypothesis testing.

APPLYING KNOWLEDGE AND UNDERSTANDING
At the end of the course student will be able to...
  • Understand the challenges derived from the presence of uncertainty in real-life situation.

  • Choose and apply adequate (basic) statistical tools to aid in the decision-making process by learning from available data.

  • Interpret charts, graphs and statistics and identify possible misrepresentations of data.

  • Question statements based on data, by analysing the statistical elements and the validity of the assumptions made.


Teaching methods
  • Face-to-face lectures
  • Exercises (exercises, database, software etc.)
DETAILS

Exercises (Exercises, database, software etc.):

  • Special sessions (delivered by a second lecturer) for the application of theoretical concepts to solving exercises. Emphasis is given to the use of statistical software R for application to real-life and simulated datasets.


Assessment methods
  Continuous assessment Partial exams General exam
  • Written individual exam (traditional/online)
  •   x x
    ATTENDING AND NOT ATTENDING STUDENTS

    The exam can be taken in two alternative ways:

    • Two partial written exams (one in the middle and one at the end of the course), with exercises and questions about theory. For students taking both partial exams, the final grade is the average of the two partial marks.
    • A written general exam with exercises and questions about theory.  

    Both formats may require the use of the computer (R statistical software) for the exercise questions.  Exam rules and program are the same for attending and non-attending students. Further information and detailed syllabus for the course are published on the Bocconi University website.
