Lesson: Cumulative Frequency Graphs Mathematics
In this lesson, we will learn how to draw a cumulative frequency diagram and how to use it to make estimations about the data.
By drawing a cumulative frequency curve, find the median of the following frequency distribution.
The table shows the distribution of daily wages of 100 workers at a factory. By drawing a cumulative frequency curve, estimate the median daily wage.
|Daily Wages (LE)||15–||20–||25–||30–||35–||40–||Total Number of Workers|
|Number of Workers||23||14||12||15||19||17||100|
If a cumulative histogram were drawn from the data given in the table, what would the highest cumulative frequency be?
