Introduction

The course provides students with a detailed overview of methods for statistical modeling and inference. The course focuses on fundamental data science topics such as descriptive analysis, basic probability theory, parameter estimation, procedures for making inference, and regression analysis. Throughout the course, students will make use of statistical software for data handling tasks and model estimation.

Learning outcomes - Knowledge

Students will learn about essential statistical concepts such as:

• Data types and methods for describing the data.
• Probability models, random variables and their characteristics, probability distributions, and linear combinations of random variables.
• Random sampling, sampling distribution, the Central limit theorem, and the data collecting process.
• Population parameters versus sample statistics, estimation, properties of estimators, and the law of large numbers.
• Statistical inference, including assumptions and the consequences of violating these assumptions.
• Data reduction and statistical models.
Learning outcomes - Skills

Students will develop important skills that allow them to:

• Analyze and describe data using methods for descriptive analysis.
• Describe stochastic phenomena using probability models and to perform simple probability calculations.
• Apply methods for parameter estimation.
• Make inference about the value of a parameter, including interpreting and presenting the results.
• Perform data handling tasks and statistical modeling using statistical software.
General Competence

The student will receive a critical and mature introduction to basic statistics and data science, which will enable students to apply statistical methods for solving real-world problems.

Course content
• Univariate and bivariate descriptive statistics and plots.
• Causation, randomization, sampling, bias and variability.
• Probability models, random variables, characteristics of random variables, and linear combinations of random variables.
• The distribution of the sample mean and the central limit theorem.
• Parameter estimation.
• Inference under exact normality and inference under more realistic conditions.
• Linear regression analysis.
• One-way ANOVA.
