Quartiles

 

In this lesson you learned that the 50th percentile divides a data set into two halves. Half the data is lower and half the data is higher at this value point, which also represents the median. Data sets can also be broken into multiple sections. A common method used by statisticians, researchers, and any person who wants to gauge and compare data to the rest is to divide the data into four equal partitions called quartiles.

 

Can you guess what percentile the first quartile represents? How about the second? The third? Draw a diagram that clearly indicates the meaning of quartiles.
