Question

The dot plots below show the number of hummingbirds spotted per day at two different feeders. The variability at each feeder is 3.168. The difference between the median number of hummingbirds spotted per day at each feeder is approximately how many times the variability?

Answer 1

≈ 3

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
