The table shows the length of hospital stay for 21 randomly selected adult patients. What is the interquartile range of this data?

To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number of points in the data set.

after you do that then say IQ=Q3-Q1
