Answer:
a)Range
Step-by-step explanation:
The range is the difference between the highest and the lowest value of a set, so it is sensitive to extreme values. That is, you can have two sets with the same mean, but with very different spacings.
For example, two grades:
set A = {40, 50, 50, 60}
set B = {0, 50, 50, 100}
The set B has a way higher range(100) than set A(20), that is, the range is sensitive to extreme values.
So the correct answer is:
a)Range
