Which method can be used to find the interquartile range for a set of data?

Q3-Q1=IQR

Step-by-step explanation:

Arrange the numbers from least to greatest then find the median of the whole set. After finding the median separate the lower half and the upper half of the data. Then find the median of the upper and lower half. The median of the lower is called the Q1 and the median of the upper half is called Q3. Finally, subtract Q1 from Q3 and this equals the IQR interquartile range).
