Worksheet: Cumulative Frequency Histogram
In this worksheet, we will practice drawing a cumulative frequency graph, given a table of values, and using it to estimate the median value from the grouped data set.
The table shows the distribution of marks students attained in a mathematics exam. By drawing a cumulative frequency curve, estimate the median mark attained.
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|
