Bar-Graph Interpretation Issues (Pop Quiz) :>

What do you find wrong with this presentation of data?

I'm not talking about the lack of time unit on the vertical scale; it's clear enough that they are talking minutes. It's not important, but the words "unit" on the chart denote "emergency-response vehicle".

ALS stands for Advanced Life Support (medic/paramedic/nurse response), and BLS stands for Basic Life Support (emergency medical technician/firefighter response).

This chart is unrelated to the pop-quiz above; It was alongside the other, and I include it in order to make the comments that follow.



I note that the Mayo Clinic (main campus) is in Rochester MN and Seattle is the birthplace of the Medic One program, but, wow, couch potatoes ought not live in Detroit, huh! :shock:

Need a hint?

BLS drivers use this chart to brag about their response times to ALS drivers.
