Testing Tufte Applying Visual Design Principles to Student Test Results Dan Gilbert (dgilbert@stanford.edu) Mike Griffin (mike@ninespeed.com) Jim Vanides (jvanides@stanford.edu) ED229C 23 January 2002
Current Design’s Strengths • High Information Density • Of Substance, Statistics and Design, 2 out of 3 “ain’t bad…” • No “Chart Junk” (eg: no unnecessary 3D…) DanGilbert, Mike Griffin, Jim Vanides
Proposed Improvements • Increase the Graphical Integrity • Minimize Non-Data Ink • Eliminate Redundant Information DanGilbert, Mike Griffin, Jim Vanides
Proposed Improvements - Graph From… DanGilbert, Mike Griffin, Jim Vanides
Proposed Improvements - Graph To… “Draw viewer’s attention to the sense and substance of the data…” DanGilbert, Mike Griffin, Jim Vanides
Proposed Improvements - Table From… DanGilbert, Mike Griffin, Jim Vanides
Proposed Improvements - Table To… Delete Redundancy (data already shown in graph) & Delete Non-Data Ink DanGilbert, Mike Griffin, Jim Vanides
