Cumulative Frequency Tables, Curves And Box Plots

Muhtasari

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.

Malengo

Draw and interpret cumulative frequency tables, curves and box plots, and find the median, quartiles, percentiles and interquartile range.

Sehemu ya kitabu Box Plots OpenStax · Introductory Statistics
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

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
