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

Answer 1

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
