1 answer:

4 0

Answer: Choice B) -4

The lower quartile, also known as Q1 or the first quartile, is the left edge of the box. In this case, that is at -4. We can drop a vertical line from the left edge of the box until we hit -4 on the number line.

Side Note: 25% of the data values are below Q1, while 75% of the data values are above Q1
