**There are two methods of creating a frequency polygon.**

**1. Less than method.**

**2 More than method.**

**You may follow the given steps to make a frequency polygon:**

**1.Less than method:**

**-- Start with the upper limits of class intervals and add class frequencies to obtain cumulative frequency distribution.**

**-- Mark upper limits along x-axis on a suitable scale.**

**-- Mark cumulative frequencies along y-axis on a suitable scale.**

**-- Plot the points (x₁, f₁) where x₁ is the upper limit of a class and f₁ is its corresponding cumulative frequency.**

**-- Join the points obtained by a line segments to get the polygon.**

**2. More than method:**

**-- Start with the lower limits of class intervals and subtract class frequencies from the total frequency to obtain cumulative frequency distribution.**

**-- Mark lower limits along x-axis on a suitable scale.**

**-- Mark cumulative frequencies along y-axis on a suitable scale.**

**-- Plot the points (x₁, f₁) where x₁ is the lower limit of a class and f₁ is its corresponding cumulative frequency.**

**-- Join the points obtained by a line segments**

**to get the polygon.**

**Hope it helps :)**

**All the best!**
