Visualisation & Underlined Psychology

sayantikabanik


Description:

Overview

We humans have been drawing insights since thousands of years ago, remember the art on the cave walls or the old beautiful handmade map you discovered in a museum? Visualization has always been around, just recently we have managed to link it with tools and technologies.

Psychology behind

Lie factor and why should we worry about it?

With the increasing complexity of graphs, we tend to forget the basic integrity principles. Lie factor is one such principle that gets subconsciously incorporated in our insights, resulting in false interpretation.

Theory behind Lie factor

Tufte introduces the “Lie Factor”, which is the ratio between the effect in the visualization and the effect in the data. So, if the effect in the data is 1, but in the visualization, it is 2, the lie factor would be 2/1 or 2. In order for the visualization to accurately represent the data, the Lie Factor should be as close to 1 as possible.

Interesting topics that I will be touching upon

  • Primal instincts of a human being
  • Lie factor (math and science behind)
  • Data evidence and established perceptions
  • Data communication and defining a direct relationship
  • A short case study
