Which scale is scaled correctly and why? explain the mistakes in the incorrect plot

The first scale is correct. They both have the correct placement for the median, which is 25, and they are both correct with the farthest spot out being 16 as it is your smallest number. The part that is wrong is that the beginning of the box part should be at 19 as that is your mode. 

Hope this helps. 

Why are u not just putting the numbers this is to much
