I would like to know if there is a study made about the cognitive strain that there is (or isnt) on reading dataheavy tables. I know there is a lot of help out there for how to make tables easier to read, but is there data as to how users read the data? Does anyone know?
My theory is that if a user find it hard to read the data but still need to evaluate different values and make the decision based on these... there is a risk that the user makes decisions based on faulty assumptions. But I have no data to show for it.
Any data, link to study or general advice would be very helpful!
