Comparing IQRs (Interquartile Range) of Two Distributions

Learn how to compare the interquartile ranges of two data distributions to assess their spread. Evaluate which data set demonstrates greater variability.

Questions

  1. MultiChoice

    Distribution A has IQR = 10, Distribution B has IQR = 4. Which distribution has greater variability in the middle 50%?

  2. MultiChoice

    Dataset 1 Q3 = 25, Q1 = 15. Dataset 2 Q3 = 30, Q1 = 12. What are their respective IQRs?

  3. MultiChoice

    What does a smaller Interquartile Range (IQR) indicate about a data set?

  4. MultiChoice

    Sample X IQR = 15, Sample Y IQR = 15. What can you conclude about their middle 50% spread?

  5. MultiChoice

    Box plot A box length is 12 units, Box plot B box length is 6 units. Which has the larger IQR?

  6. MultiChoice

    How is IQR calculated from a box plot?

  7. MultiChoice

    Plant Group 1 IQR = 3 cm, Plant Group 2 IQR = 8 cm. Which group has more consistent middle growth?

  8. MultiChoice

    If Dataset A IQR is 8 and Dataset B IQR is 16, how do their spreads compare?

  9. MultiChoice

    Brand X battery life IQR = 2 hours, Brand Y battery life IQR = 7 hours. Which brand is more predictable in performance?

  10. MultiChoice

    What portion of the data set is represented within the IQR?

  11. MultiChoice

    Group A IQR = 5, Group B IQR = 10. What is the difference between their IQRs?

  12. MultiChoice

    Why is IQR preferred over Range when outliers are present?
