Seeing Statistics

Posted by Armando Brito Mendes | Filed under estatística, lições, materiais ensino, visualização

Uma excelente maneira de aprender estatística com um webBook dinâmico e muito visual

Seeing Statistics ® is a new approach to teaching statistics using the World Wide Web. This webbook is based on three premises:

• The important principles of statistics are remarkably easy if they can be seen.
  
• Active involvement of the student facilitates learning.
• Statistics can be fun!

Most of the graphs and figures in this textbook are dynamic and under the  control of the reader. Interacting with the graphs allows you to see the important statistical principles in action.

Rather than talk about it, it is best to view Seeing Statistics in action. To access Seeing Statistics, click on the “Enter Seeing Statistics” button to begin your exploration of Seeing Statistics!
