Lie with Statistics – Learn How to Create Misleading Bar Charts – use a Photograph instead of a bar… constrain porportions/aspect ratio to exaggerate change.

March 5, 2018

Bar charts that use a resized photograph instead of a bar Automatically give the viewer an exaggerated idea… RESIZE the photo using constrained proportions. This gives the illusion that a increase of Two times is displayed as a Four times increase in area. This technique was used a lot by the newspaper USA TODAY.

Normal, Accurate Bar Chart.

Distorted Chart Using a Re-Sized Photo instead of bars in the bar chart. Double the Height = Four Times the Area. Visually Exaggerating Change. It’s an Illusion. A Magic trick. The viewer automatically assumes that the change in data over time is much more significant that actual reality.

Compare the two charts. What do you see? Report results in the comments section below. It appears to me that the bottom chart shows a situation that is More Significant than the top chart…

I learned this from Dr Kim of Humboldt State University. Thanks! Dr. Kim.
