This is an example of how statistics can be used to skew results: Maryland’s Health Department counts number of tests done to determine the positivity rate, so if a person is tested multiple times with negative results each time, those results each count. Johns Hopkins uses a much more accurate rate, counting each person tested (“Maryland reports 356 new coronavirus cases as Hopkins positivity rate continues to climb,” Sept. 8). The only way the statistics would truly be accurate is if there were universal testing.
