Calculate the interquartile range using the following data: 8 10 10 10 12 12 12 12 12 12 12 14 14 16 16 16 16 17 18 20.
What will be an ideal response?
4.
Q1 = Value of case number (20 + 1)(.25) = Value of case number 5.25 = 12 and Q3 = Value of case number (20 + 1)(.75) = Value of case number 15.75 = 16. Now calculate the interquartile range using the formula, Q = Q3 – Q1 = 16 – 12 = 4
