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

(C) Infoseg 2013

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

Type 1 Comments

(C) Infoseg 2013

Type 2 Comments

(C) Infoseg 2013

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
