≈ 3

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached photo.

My answer:

The median number is the middle value of the dot plots

  • In the feeder 1: 24 24 24 24 26 26 28 28 28 28 28 32 32 34 34 34 34 34 36

=> the median number is: 28

  • In the feeder 2: 10 12 12 12 14 14 16 16 16 16 16 18 18 20 20  20  20  20  20  20  22 22 22 22 22

=> the median number is: 18

=> The difference between the median number of hummingbirds spotted per day at each feeder is: 28 -18 =10 and it is = 10 / 3.168

≈ 3 times  the variability
