They're at it again. Once more, the White House is using a bar chart to plot cumulative test numbers--without even labeling the numbers as cumulative, May 2020 ~ @CT_Bergstrom
Here's a remarkable example of a misleading visualization from the 4/6 White House press conference. They are using a bar chart to show *cumulative* tests run. Looks impressive, but that linear increase means capacity is not improving! h/t @markjaggers ~ @callin_bull

Statistical tests calculate whether the difference between two sets of results is significant enough for us to be confident that any changes seen in the dependent are due to manipulation of the independent variable.

In just 15 days the total number of #COVID19 cases in Georgia is up 49%, but you wouldn't know it from looking at the state's data visualization map of cases. The first map is July 2.

Scenario 2: This time, of the 100 people the officer sees, he stops 50. But this time he is biased in whom he pulls aside...
