  9. We plot cumulative frequency against upper class value.

  10. We plot cumulative frequency against upper class value.

  11. We plot cumulative frequency against upper class value.

  12. We plot cumulative frequency against upper class value.

  13. We plot cumulative frequency against upper class value.

  14. The median is the 90th value The median is about 163 cm

  15. The lower quartile is the 45th value The lower quartile is about 155 cm

  16. The upper quartile is the 135th value The upper quartile is about 170 cm

  17. The Interquartile Range = upper quartile — lower quartile = 170 — 155 = 15 cm
