Intermediate screencast on plotting a cumulative frequency curve from the frequency distribution.
  • What is a cumulative frequency curve?
  • How do you calculate the cumulative frequencies of a data set?
  • What are the upper class boundaries for each interval of a data set?
  • How do you plot the cumulative frequency curve for a data set?
  • How do you find the median value for a data set from a cumulative frequency curve?
  • How do you find the upper and lower quartiles for a data set and what do quartiles mean?
  • How do you find the inner-quartile range for a data set and what does it mean?
  • What should a cumulative frequency curve look like?
  • What does the inner-quartile range tell you about a data set?
This lesson goes step by step through a cumulative frequency curve for a data set. All parts of this method are explained and shown clearly and slowly. This is a wonderful tutorial to learn the basics of this method of plotting a cumulative frequency curve and finding values from the curve.
