Question

     29. Explain the method of constructing frequency polygon with an example.​

Answer 1

$\color{blue}\huge\mathsf{Answer}$

Note that the above method is used to draw a frequency polygon without drawing a histogram. You can also draw a histogram first by drawing rectangular bars against the given class intervals. After this, you must join the midpoints of the bars to obtain the frequency polygon.

Explain the method of constructing frequency polygon with an example.

Answer ⤵️

To draw frequency polygons, first we need to draw histogram and then follow the below steps:

Step 1- Choose the class interval and mark the values on the horizontal axes

Step 2- Mark the mid value of each interval on the horizontal axes.

Step 3- Mark the frequency of the class on the vertical axes.

Step 4- Corresponding to the frequency of each class interval, mark a point at the height in the middle of the class interval

Step 5- Connect these points using the line segment.

Step 6- The obtained representation is a frequency polygon.
