This training is a proper introduction to using statistics methods and gives a solid basis for a future development in Data Science. The ability to use elements of probabilistic calculus and statistics methods is necessary for every Data Scientist. The training is conducted by very experienced experts of Data Science.

The training is divided into two parts. The former is concerned with the revision of the most important issues of statistics which are crucial for people interested in data analysis. The latter deals with the presentation of the most frequently used methods of statistics learning by using data. Each presented element is followed by a number of exercises which will make the learning process easier and quicker. The training is conducted in the most popular data science languages – R and Python.

## Who is this training for?

This training is the introduction to Data Science. It means that all important elements of Statistics which are crucial in Data Analysis are covered in this training. If you are interested in revising the knowledge of Statistics and obtain the practical abilities in statistical data analysis then this training is what you need.

## What will I learn?

After completing the training, you will:

• Understand the basics of Theory of Probability and Statistics
• Use basic statistical measures to describe the data
• Construct confidence intervals for statistics
• Verify statistical hypotheses and understand the idea of testing
• Learn how to properly use charts in data analysis
• Understand the concept of Bayesian approach in statistics
• Get to know methods of statistical learning from data
• Learn how to properly clean data for analysis
• Learn how to use linear regression and its non-linear extensions
• Learn how to use statistical classification methods
• Learn how to use methods of clustering and association rules
