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.
Oh, dude, it's like this: a histogram is like a bar graph that shows the frequency of data within specific intervals, while a frequency polygon is a line graph that connects the midpoints of the intervals in a histogram. So, it's like the difference between drawing bars and connecting dots. Cool, right?
A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.
frequency is the kinds of the line graph, bar graph, picture graph, pie graph. that's all
A bar graph cannot have classes with different width. The height of a bar graph represents the frequency attributed to that class whereas in a histogram the area of a "bar" is proportional to the frequency, the height represents the frequency density.

In a Frequency Polygon, a line graph is drawn by joining all the midpoints of the top of the bars of a histogram. A frequency polygon gives the idea about the shape of the data distribution. The two end points of a frequency polygon always lie on the x-axis.
graph?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
The main difference is that the vertical scale for a frequency graph is in units (or numbers) whereas in a percentage graph, it is in percentages,
A bar graph cannot have classes with different width. The height of a bar graph represents the frequency attributed to that class whereas in a histogram the area of a "bar" is proportional to the frequency, the height represents the frequency density.
By its very nature, measuring cumulative frequency on either axis of a graph will produce a continuing line on the opposite axis. Therefore, it is impossible to construct a closed frequency polygon when dealing with cumulative frequency.
It could be a bar graph or a frequency polygon. Or, if the intervals are of different sizes, a histogram.
