Making Graphical Inferences: A Hierarchical Framework
Raj M. Ratwani, J. Gregory Trafton · eScholarship (California Digital Library) · 2004
A hierarchical framework suggesting how graph readers go beyond explicitly represented data to make inferences is presented.According to our hierarchical framework, graph readers use read-offs, integration and pattern extrapolation to make inferences.Verbal protocol data demonstrates highlevel differences in the way inferences are made and eye track data examines these processes at the perceptual level.
