Cumulative relative frequency statistics
Webf. To figure out what % of welders make less than $20 per hour, we look at the cumulative relative frequency of $20 and read off the corresponding percentage on the y-axis. From the graph, we can see that the cumulative relative frequency for $20 is roughly 50%, which suggests that half of the welders make less than $20 per hour. WebApr 9, 2024 · Using the graph, we can estimate the quartiles of the distributions by where the line graph crosses cumulative relative frequency values of 0.25, 0.50 and 0.75. The 1 st Quartile is about 87 minutes. The median is about 100 minutes. The 3 rd Quartile is about 108 minutes. Example: Comparing weights of apples and oranges
