Question

Aliyah interviewed 20 people who each have just one sibling. She asked them what the difference in age, in years, is between them and their siblings. The line plot below shows Aliyah’s data.

Aliyah removes the point representing the 10-year age difference from her data. Which measure changes the least in value when this point is removed from Aliyah’s data

Answer 1

I believe the question is asking which would be the least in value now that 10 is removed from the data chart. So since 10 is removed 5 would be the point that is the least in value.
I hope this helped you answer the question :)
