# Introduction to Statistics and Data Science for Management

## Course Description

This course introduces to the theory and practice of describing and analysing data, testing hypotheses and how to use the free statistical computing software R for your data analyses.

Topics discussed include, but are not limited to, combinatorics, probability, random variables, density and distribution functions, sampling from a population, sample properties and descriptive summary statistics, and inferring population characteristics from a random sample.

## Course Objectives

The course will enable students to describe and to analyse data using simple statistical methods and to interpret and to report their data analysis results. Students will learn how to use the statistical computing software R, a software widely used in academia and industry.

## Course Materials

### Required:

The course does not follow a single textbook, there will be weekly, mandatory reading assignments from different sources as indicated under the topics below.

## Course Requirements:

Students must read the weekly reading assignments before each session. Students need access to a computer with the statistical computing software R. The software is available free of charge from www.r-project.org. As a graphical frontend RStudio is recommended. Alternatively, students can create an account at https://rstudio.cloud to get access to an in-browser version of RStudio.

## Grading Guidelines:

Grading Component | Weight |
---|---|

Problem Sets | 40% |

Data Analysis Project: Report | 50% |

Data Analysis Project: Presentation | 10% |

## Workload

A typical 3 US credits / 5 ECTS course requires 150 hours of your time. The table below identifies how I expect those 150 hours will be allocated. While you do not receive direct marks for reading, reading will affect your ability to participate in class discussions and activities and your ability to succeed in the assessments and therefore your final grade.

Activity | Time |
---|---|

Class Time (3 hours / week) | 45 hours |

Reading (4 hours / week) | 60 hours |

Problem Sets (2 hours / week) | 30 hours |

Preparation and Review (1 hour / week) | 15 hours |
