3 questions to ask yourself next time you see a graph, chart or map

Take for example the bar graph presented at an April 6 press briefing by members of the White House Coronavirus Task Force. It’s titled “COVID-19 testing in the U.S.” and illustrates almost 2 million coronavirus tests completed up to that point. President Trump used the graph to support his assertion that testing was “going up at a rapid rate.” Based on this graphic many viewers likely took away the same conclusion – but it is incorrect.

The graph shows the total cumulative number of tests performed over months, not the number of new tests each day. …

Color plays an important role in how people interpret information. Color choices can make you notice particular patterns or draw your eye to certain aspects of a graphic.
