The figure at the right shows a cumulative frequency graph
30 lis 2022 · How do I use and interpret a cumulative frequency graph? A cumulative frequency graph provides a way to estimate key facts about the data median, lower and upper quartiles and interquartile range
Cumulative frequency is the total of a frequency and all frequencies in a frequency distribution until a certain defined class interval. Learn more about the interesting concept of cumulative frequency, the types, plotting a graph, and solve a few examples.
A cumulative frequency graph, or ogive is a line graph displaying the cumulative frequency of each class at its upper class boundary. The upper boundaries are marked on the horizontal axis,
Summary. Cumulative frequency graphs are to estimate the median and quartiles when data is grouped. Drawing a cumulative frequency curve: Add an extra column to the table and find the cumulative frequency (i.e. running total) Draw the axes — cumulative frequency is always on the vertical axis.
