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!

Ternary Diagrams Using R

Ternary Diagrams Using R: An Example Using Election Outcomes
A tutorial by D. M. Wiig
In part one of this tutorial I discussed creating a ternary diagram using a simple data frame that contained five hypothetical cases. In this tutorial I will expand on that foundation by creating a more informative ternary diagram using live data.
A useful application of this package in social science research is creating a visual display of parliamentary election outcomes. Specifically we can use a ternary graph to examine the distribution of seats in the British House of Commons over a period of time. Since the UK uses a proportional system to allocate seats in the House of Commons there can be a variety of outcomes in any given national election.

Formas alternativas de instalar novos nós no KNIME
Download KNIME Features using the KNIME Update Site
Additional KNIME plug-ins can be obtained via the KNIME update site which contains additional nodes/functionality for the KNIME workbench:
http://update.knime.org/analytics-platform/2.12/
Alternatively, the KNIME update sites can be downloaded as a zip file:
The KNIME Analytics Platform as well as all other KNIME products are linked automatically to the KNIME Update Site through the File menu via the “Install KNIME Extensions” command. We recommend using this command to access the KNIME Update Site.
If you are using KNIME SDK, a pre-existing Eclipse installation, or are working in an environment with limited internet access, another option for installing KNIME extensions is available. To access this additional dialog use the Help -> Install New Software command. This tool has a different interface that allows update sites to be manually specified. Clicking on “Add…” button (illustrated below) will allow you to either manually specify the url of the KNIME Update Site or use the offline (.zip) version of the Update Site to customize your KNIME installation.
Note: It is important not to unzip the archived KNIME Update Site file prior to specifying it as an update source for KNIME.

Real Chart Rules to Follow

Excelente guia sobre construção de gráficos para representar dados.
There are a lot of “rules” for visualization. Some are actual rules, and some are suggestions to help you make choices. Many of the former can be broken, if that’s what the data dictates and you know what you’re doing.
But, there are rules—usually for specific chart types meant to be read in a specific way and with few exceptions—that you shouldn’t break. When they are, everyone loses. This is that small handful.
