The frequency polygon happens to be a special line graph whose use takes place in statistics. One can draw these graphs either separately or combined. One can make use of the information that is available in a frequency distribution table for drawings of these graphs. Question 4: Differentiate between a frequency polygon and frequency curve?
A frequency polygon is a closed figure that is formed by joining the top midpoints of all the rectangles of histograms using a straight line. Whereas frequency curve is a curve that is obtained by joining the top midpoints of all rectangles of a histogram using a free hand.
For drawing a frequency polygon of a continuous frequency distribution, we plot the points whose ordinates are the frequencies of the respective classes and abscissae are respectively (a) upper limits of the classes (b) lower limits of the classes (c) class marks of the classes (d) upper limits of preceding classes
We will take the marks on x-axis and the cumulative frequency on the y-axis. The points to be plotted are ( 10 , 7 ) , ( 20 , 17 ) , ( 30 , 40 ) , ( 40 , 91 ) , ( 50 , 97 ) a n d ( 60 , 100 ) . Once, we join this points, we will get the required less than cumulative frequency polygon, as shown in the graph given above.

Representing cumulative frequency data on a graph is the most efficient way to understand the data and derive results. Learn more about Frequency Polygon here. There are two types of Cumulative Frequency Curves (or Ogives) : More than type Cumulative Frequency Curve; Less than type Cumulative Frequency Curve; More Than Type Cumulative Frequency ...
Frequency Distribution; Histogram; Frequency Polygon Cumulative Frequency Graph or Ogive; Construction of a Bar Diagram. Draw two perpendicular lines intersecting each other at a point O. The vertical line is the y-axis and the horizontal is the x-axis. Choose a suitable scale to determine the height of each bar.
