Which two locations have the greatest overlap in their distributions?
Choose exactly two answers that are correct.
Location Mean MAD
Emerald Lake
20.7
3.0
Kennedy Falls
25.6 2.8
Pine Meadows
14.8 2.9
Spruce Grove
19.2 3.1

Best ResponseYou've already chosen the best response.0You add and subtract the MAD from the mean to find the range. Mean 20.7 and MAD 3.0 means range is from 17.7 to 23.7 for Emerald Lake. I'd do the same thing to the other options and then you can compare the ranges.

Best ResponseYou've already chosen the best response.0Actually, you don't need to do that. The MAD's are all pretty close to 3, so just pick the 2 with the closest means.

Best ResponseYou've already chosen the best response.0That would be 25.6 and 14.8, a difference of 10.8. Can you find any other pair with a smaller difference. You were on the right track with A

Best ResponseYou've already chosen the best response.0So, one of the answers was A. Okay. So maybe A and D.

Best ResponseYou've already chosen the best response.0That's the smallest difference, so would have the most overlap.
