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 A line chart or frequency polygon is based on?
It is based on some data.
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.
Which polygon has no of sides equal to diagonal?
The formula for the number of diagonals in a polygon is s*(s-1)/2 - s To find such a polygon, we solve for when that formula equals s s*(s-1)/2 - s = s s*(s-1)/2 = 2s (s-1)/2 = 2 s-1 = 4 s = 5 Thus, the polygon with this property is the pentagon.
If the sum of interior angle measures of a polygon is 900 degrees how many sides does the polygon have?
The polygon has 7 sides (septagon). The formula for the total degrees is D = 180 (s-2) 900 = 180 (s-2) 5 = s-2 7 = s
What are frequency Polygon?
Frequency polygons are graphical devices used for understanding the shapes of distribution.
What is A graphic representation of a frequency distribution constructed by connecting the class midpoints with lines?
This is called a frequency polygon.
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.
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 are advantages and disadvantages of frequency polygon?
A frequency polygon is not very effective in displaying group data when the class sizes are not the same.
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 a cumulative frequency polygon?
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.
What are the uses of frequency polygon graph?
A frequency polygon graph is used to visually represent the distribution of a dataset, highlighting the frequency of various values or intervals. It helps in identifying trends, patterns, and the shape of the distribution, making it easier to compare multiple datasets. Frequency polygons are also useful for detecting outliers and understanding the overall spread of data, and they can be used alongside histograms for a more comprehensive analysis.
What is Frequency curve?
A frequency curve is a graph obtained by joining the points of a frequency polygon freehand smoothly.
How do you form a frequency polygon from a frequency diagram?
Identify the midpoint of the top of each bar of the frequency diagram. Join these together and they will form a frequency polygon. Sometimes the polygon is extended down to the horizontal axis to where the midpoints of the bar before the first bar would have been and where the bar after the last bar would have been.
What is another name for a cumulative frequency polygon?
Ogive
Another name for cumulative frequency polygon?
OGIVE
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.
What is five letter name for cumulative frequency polygon?
graph?
What is another name for cumulative frequency polygon?
It is called an ogive.
The difference between a histogram and a frequency polygon is?
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?
Is frequency polygon proportional to class frequency?
No, a frequency polygon is a type of data visualization that uses line segments to connect points representing the frequencies of different classes. It shows the distribution of data values, but it does not necessarily represent the actual class frequencies.

What is A line chart or frequency polygon is based on?
