Class Statistics II

The purpose of this course is to introduce probability distribuition models and the basic principles of Inferential Statistics. Students should understand the usefulness and wide application of these methodologies to various contexts, particularly in their subject areas. It is intended that students develop their thinking skills, helping them to address and solve real practical problems in their area of study or in other contexts.
