Answer & Solution
Correct answer: B. The middle half of the data
1. The interquartile range is built from the two quartiles.
2. It is the difference between the third quartile and the first quartile.
3. The interquartile range is a number that indicates the spread of the middle half, or the middle 50 percent, of the data.
4. Because it ignores the tails, it is not disturbed by extreme values.
