How do you find the first quartile on a box plot?
The outer lines of the IRQ show the first and third quartiles, so if you are looking at the lower half of the data, then the edge of the IRQ, where the IRQ and whisker meet, is approximately one half of the lower half of the data. In other words, the first quartile is the median of the lower half of the data. What are box plot whiskers?
