Cumulative Frequency Tables, Curves And Box Plots
Bayani Gaba-gaba
When data is grouped, a cumulative frequency table keeps a running total as you move through the groups. Plotted as a curve, it lets you read off the median and quartiles, and a box plot then summarizes the whole spread at a glance.
In this lesson you will build cumulative frequency tables, draw and read cumulative frequency curves to find the median and quartiles, and use those values to draw and interpret a box plot.
Manufura
- Draw and interpret cumulative frequency tables, curves and box plots, and find the median, quartiles, percentiles and interquartile range.

Box Plots
Box plots (also called box-and-whisker plots or box-whisker plots ) give a good graphical image of the concentration of the data. They also show how far the extreme values are from most of the data. A box plot is constructed from five values: the minimum value, the first quartile, the median, the th

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
