# EBA 2904 Statistics

## EBA 2904 Statistics

This course gives an introduction to statistics. Main themes are descriptive statistics, probability and hypothesis testing. Formulas and formal procedures play an important role, but the emphasis is on developing statistical literacy and critical thinking.

After compledted course students shall:

- Understand the relevance of statistical analysis in economics and marketing
- Acuire knowledge of basic concepts and overview of statistics
- Understand the difference between a population and a sample
- Understand what a random variable and a statistical model is
- Understand that statistical methods are based on assumptions that must be checked
- Understand what estimation and hypothesis testing is about
- Be acquainted with the statistical and mathematical notations used in statistics

After completed course students will be able to:

- Discern randomness from real underlying effects
- Use statistical software and interpret computer displays from such software
- Produce statistical graphics
- Compute probabilities and confidence intervals
- Conduct the most basic types of hypothesis testing and estimation
- Reflect on the role of randomness

Students will understand that in many situations a statistical analysis will help making better decisions, but also be ware that statistical methods can be wrongly applied and lead to false conclusions.

- Probability. Basic definitions. Limits of relative frequencies.
- Introduction to Monte Carlo simulation.
- Random variables and their distributions. Approximating distributions through Monte Carlo simulations: Histograms as approximations to densities.
- The law of large numbers and the central limit theorem illustrated through Monte Carlo simulations.
- Confidence intervals and hypothesis testing in large samples. A brief summary of the t-test under normality assumptions.
- Correlation and simple linear regression.
- Assessing the performance of statistical procedures using Monte Carlo simulations.

There are 48 course hours, some of which will be used for instructions in the computer software Python.

__Work requirements__

There are 8 mandatory multiple choice tests to be answered in It's Learning.

If a test is not approved in the first try, the student can retry. It is mandatory that the student get approved at least 5 of these tests in order to take the final exam.
