They are the same thing except that in a histogram you are using bars (like in a bar chart) to show the frequency, while a polygon uses points connected by straight lines
The way I have the students do it is to plot the x,y coordinates for your data ( x is the value of the random variable, y is the frequency )
If you are doing a frequency polygon, you just connect the dots with straight lines (you need to start at zero to the left of your first point and to the right of your last point)
If you are doing a histogram, just draw bars where the middle of each bar comes up to the x,y point

The difference between a histogram and a frequency polygon is?
the basic difference between histogram and frequency polygon is that histogram uses bars to show its frequency and frequeny polygon uses points and join its staight line
How do you create a percentage frequency histogram?
what is the difference between a regular histogram and a percent frequency polygon
What is difference between frequency polygon and line graph?
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.
How do you draw frequency polygon without using histogram?
You draw a series of line segments joining the points which would be the middle of the top of each bar of the histogram.
What is the difference between a cummulative frequency graph and a cumulative frequency polygon?
A cumulative frequency polygon has straight lines connecting the points. A normal cumulative frequency diagram uses a smooth curve to join the points.

What is the difference between a histogram and polygon?
1. A histogram is two-dimensional while a polygon has more than four dimensions. 2. A histogram may be drawn from a histogram by joining the mid points of upper horizontal sides of each rectangle. But a histogram can not be drawn from a polygon. 3. The frequency polygon of several distributions can be plotted on the same axis while more than one histogram can not be drawn on the same axis. 4. It is possible to compare the polygon of several distributions as they can be plotted on the same axis. But to compare histogram we must have a graph for each distribution. 5. Polygon an outline of data pattern is sketched more clearly than histogram.
What is a frequency polygon graph?
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.

What is the difference between an ogive and a frequency polygon?
The ogive never close because they represent non-decreasing functions, and polygon you close it.
What are the three basic forms of statistical presentation?
bar graph,histogram and frequency polygon are the three basic forms of statistical representation
What is a bar graph that shows the number of data items that occur within each interval?
It could be a bar graph or a frequency polygon. Or, if the intervals are of different sizes, a histogram.
How is a frequency curve in statistics different from a frequency polygon?
In order to plot the points on either the frequency polygon or curve, the mid values of the class intervals of the distribution are calculated. Then the frequencies with respect to the mid points are plotted. However in a frequency curve the points are joined by a smooth curve, where as in a frequency polygon the points are joined by straight lines. Apart from this major difference, a frequency polygon is a closed figure where as the frequency curve is not.
What is the difference between a polygon and a curve?
well a polygon has angles and a curve has none.
