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.

Measures of the Location of the Data
The common measures of location are quartiles and percentiles Quartiles are special percentiles. The first quartile, Q 1 , is the same as the 25 th percentile, and the third quartile, Q 3 , is the same as the 75 th percentile. The median, M , is called both the second quartile and the 50 th percenti

Frequency, Frequency Tables, and Levels of Measurement
Once you have a set of data, you will need to organize it so that you can analyze how frequently each datum occurs in the set. However, when calculating the frequency, you may need to round your answers so that they are as precise as possible. A simple way to round off answers is to carry your final
