For a skewed data set, we say that a data set doesn't vary much if a. (Q3 - Q1) / Median ≤ .5 b. (Q3 - Q1) / Median > .5 c. Standard deviation / mean > .5 d. Standard deviation / mean ≤ .5

The option b) is correct

Step-by-step explanation:

Given that " For a skewed data set, we say that a data set doesn't vary much "

To say a skewed data set doesn't vary much :Here Mean is 0.5For a skewed data set we have Median is always greater than MeanThat is Median > Mean=0.5Therefore Median > 0.5

Median is closer to >

For a skewed data set, we say that a data set doesn't vary much if

Therefore the option b) is correct

I’m not positive but i think it’s none of your buisness
