Statistical Analysis with R and Mind Mapping automation

Information overload in Statistical Analysis
• Very powerful tools to generate statistical information (R)
• Linear visualization of the information
• Lots of information in numerical and graphical form
• No links between information elements
(C) Infoseg 2013
Mind Mapping automation as a possible solution
• Tree structure • Grouping of related elements • Links between elements • Visual elements to improve display • Hyperlinks • Automatic generation of the Maps • Easy presentation of the information • Multimedia capabilities • A single compressed file • Free viewer

Example
• Investigating the effects of sports-related concussion
• Simulated data are based on an online assessment tool called IMPACT (http://www.impacttest.com)
• Example taken from Coursera Statistics 1 course Princeton University
(C) Infoseg 2013
Caution
• This is just a very simple example
• Complexity can be increased to any level
• This can be done manually or (preferably) using Mind Mapping automation
• The system can be used by teachers, students or researchers

Comments about the comments
• They have to be added manually by the teacher
• There are several possible types of comments
• All types can be used in a Mind Map

Conclusion
(C) Infoseg 2013
Conclusion
• Mind Mapping is a very interesting technique to use in the visualization of Statistical Analysis results
• You can do it manually (In case you have a lot of free time)
• It is better to do it using Mind Mapping automation
