STATISTICS 101

We constantly listen to information supported by “statistical data”. Every detail (and the opposite) is "scientifically proven." Without a basic knowledge of Statistics it is impossible to understand the information we receive to make a serious judgment of its veracity.

In this course essential concepts are studied to understand the information, for the management of the company, for the decision making based on the information: How to represent the information? What do the graphs say? What do we mean? How to interpret the information contained in the data to know what decisions to make? The course will be focused on learning through solving problems that cover different areas of the participants' performance.

Differentiator

The knowledge and techniques that are studied are introduced from the approach and resolution of problems related to the different and diverse areas of performance of the participants.

For the introduction of each concept, the following steps are followed:

Statement of a problem
Analysis of the variables involved: information they contain, types, distributions.
Presentation of statistical concepts
Application of the concept to the problem. Discussion of the solution
Getting Results Using Python, R, IBM SPSS Modeler or personalized
