### Course Syllabus

#### Abstract

This course is designed to introduce students to the basic ideas and methods of statistics as well as the application of statistical methods in econometrics, data science and the social sciences. This course provides some of the analytical tools that are required by advanced courses of data science and machine learning. This course provides students with experience in the methods and applications of statistics to a wide range of theoretical and practical situations. The course is taught in English. Prerequisites are Calculus (functions of several variables, partial derivatives, integrals, maximum of functions), and elements of Linear algebra (vectors, matrices, linear equations).

#### Learning Objectives

• This course introduces some of the basic ideas of theoretical statistics, emphasizing the applications of these methods and the interpretation of tables and results.
• We will introduce concepts and methods that provide the foundation for more specialised courses in statistics.

#### Expected Learning Outcomes

• Students will be able to routinely apply a variety of methods for explaining, summarising and presenting data and interpreting results clearly using appropriate diagrams, titles, and labels when required.
• Students will be able to summarise the ideas of randomness and variability and the way in which these link to probability theory to allow the systematic and logical collection of statistical techniques of great practical importance in many applied areas.
• Students will have a grounding in probability theory and some grasp of the most common statistical methods.
• Students will be able to recall a large number of distributions and be a competent user of their mass/density and distribution functions and moment generating functions.
• Students will be able to perform inference to test the significance of common measures such as means and proportions and conduct chi-squared tests of contingency tables.
• Students will be able to use simple linear regression and correlation analysis and know when it is appropriate to do so.
• Students will be able to apply and be competent users of standard statistical operators and be able to recall a variety of well-known distributions and their respective moments.
• Students will be able to explain the fundamentals of statistical inference and apply these principles to justify the use of an appropriate model and perform hypothesis tests in a number of different settings.
• Students will demonstrate an understanding that statistical techniques are based on assumptions and the plausibility of such assumptions must be investigated when analysing real problems.
• Students will be able to explain the principles of data reduction.
• Students will be able to choose appropriate methods of inference to tackle real problems.

#### Assessment Elements

• First semester Home assignments and Quizzes
• Second semester Home assignments and Quizzes
• FallMock (October Midterm)
At the end of each module the students sit a written exam.
• SpringMock (Spring Midterm)
At the end of each module the students sit a written exam.
• WinterExam (December Exam)
At the end of each module the students sit a written exam.
• University of London exams (May Exam)
