Examples
1. Find Arithematic mean for data `2,3,4,5,6`

Solution:
AM `=(x_1+x_2+x_3+x_4+x_5)/5`

`=(2+3+4+5+6)/5`

`=20/5`

`=4`

---

2. Find Arithematic mean for data `5,4,6,3,7,5`

Solution:
AM `=(x_1+x_2+x_3+x_4+x_5+x_6)/6`

`=(5+4+6+3+7+5)/6`

`=30/6`

`=5`

3. Find Arithematic mean for data `3,4,5,4,6,3,3`

Solution:
AM `=(x_1+x_2+x_3+x_4+x_5+x_6+x_7)/7`

`=(3+4+5+4+6+3+3)/7`

`=28/7`

`=4`

---

4. Find Arithematic mean for data `18,14,15,19,15,20,12,15,16`

Solution:
AM `=(x_1+x_2+x_3+x_4+x_5+x_6+x_7+x_8+x_9)/9`

`=(18+14+15+19+15+20+12+15+16)/9`

`=144/9`

`=16`
