Which measure of variation is very sensitive to extreme values?

a)range

b)mean

c)histogram

d)median

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

it would be 6xy and -16xy.
