Organizing the data into a frequency distribution may make patterns within the data more evident.

The difference between frequency polygon and line graphs is their purpose. Frequency polygons are for understanding shapes distributions, while line graphs shows information that is related in some way.

A histogram is when the bars are touching and it graphs what you have on your frequency table.

frequency table helps us organize data in a categorial or norminal way.
Graphs and statistics was very helpful in the distribution of wealth in 1920s.
In a bar graph, the height of the bars is relative to the frequency. In a histogram, the area of the bars is relative to the frequency. Because it deals with area, the label on the y-axis is "frequency density" rather than just "frequency"
