Objectives
In today's world there is an enormous amount of information available. There are diverse sources and many of them are accessible through the Internet. To analyze this information and draw valid conclusions we need to use specific techniques. The most widely used and successful technique are based on Statistics. In this course we will learn how to obtain information from the data with techniques that you will use both in your studies and in your professional career, because these techniques are commonly used by most companies and organizations. Today a statistical analysis is inconceivable without computer resources. Therefore the teaching of Statistics will rely heavily on computer laboratories. After completing this course, you should be able to extract information from the data and draw scientific conclusions, and to express those conclusions in a written report. Also, you can establish relationships between variables using the regression model and to interpret the model properly.
