Frequency Polygon: Definition, Steps to Draw, Examples, Uses
2024年4月25日 · Frequency Polygons in Statistics: A frequency polygon is a type of line graph where the frequencies of classes are plotted against their midpoints. This graphical representation closely resembles a histogram and is typically used for comparing data sets or showing cumulative frequency distributions.
Frequency Polygons - Definitions, Steps, Formula, Example
Frequency polygons are a type of line graph that helps in providing accurate data through a curved shaped line. Learn more about this interesting concept of frequency polygons, steps to plot, and solve a few examples.

2.5: Frequency Polygons - Statistics LibreTexts
2022年4月23日 · To create a frequency polygon, start just as for histograms, by choosing a class interval. Then draw an X X -axis representing the values of the scores in your data. Mark the middle of each class interval with a tick mark, and label it with the middle value represented by the class. Draw the Y Y -axis to indicate the frequency of each class.
Frequency Polygon - GCSE Maths - Steps, Examples & Worksheet
How to draw a frequency polygon. In order to draw a frequency polygon: Calculate the midpoint of each class interval. Plot the class frequency at the midpoint for the class. Connect the plotted values using straight line segments.
2.3: Histograms, Frequency Polygons, and Time Series Graphs
2023年4月2日 · To construct a frequency polygon, first examine the data and decide on the number of intervals, or class intervals, to use on the x-axis and y-axis. After choosing the appropriate ranges, begin plotting the data points.
Frequency Polygon: Definition, Steps to Draw, Videos, Solved
Frequency polygons give an idea about the shape of the data and the trends that a particular data set follows. Let us learn the step by step process of drawing a frequency polygon, with or without a histogram.
Frequency Polygon | Meaning, Steps to Draw and Examples
2024年7月28日 · (I) Steps to Draw Frequency Polygon in Discrete Series. The steps required to construct a frequency polygon in the case of discrete series are: Write the values of the given variable (say, X) on the X-axis and the corresponding frequencies on the Y-axis. Draw a straight line connecting the points of the various frequencies.
Frequency diagrams and frequency polygons - KS3 Maths - BBC
A frequency polygon can be created for the same set of data. Instead of drawing bars, plot the midpoint of the class interval and the frequency. These points are joined by line...
2.2: Histograms, Ogives, and Frequency Polygons
2021年2月6日 · To create a histogram, you must first create the frequency distribution. The idea of a frequency distribution is to take the interval that the data spans and divide it up into equal subintervals called classes. Pick the number of classes to use. Usually the number of classes is between five and twenty.
