Cumulative Frequency Diagrams
Bayani Gaba-gaba
A cumulative frequency diagram adds up frequencies as you go, building a smooth rising curve that reveals the median and the spread of a data set at a glance. It is the key to reading quartiles and percentiles from grouped data.
In this lesson (Extended tier) you will draw and interpret cumulative frequency tables and diagrams, and estimate the median, quartiles, percentiles and interquartile range from the curve.
Manufura
- Draw and interpret cumulative frequency tables and diagrams.
- Estimate and interpret the median, percentiles, quartiles and interquartile range from cumulative frequency diagrams.
