TOPIC FOUR: "MEASURES OF DISPERSION : PART 3" 

Definition:

What is MODE? 

Mode is many, Repeating and etc. Other definition is a number that appears most often in set of numbers. 

The first step to find Mode is ARRANGE THE NUMBER IN ASCENDING ORDER (if possible), second, you just need to find the that appears most often. 

Examples:

1. {1, 2, 2, 3, 4, 5, 2, 6, 7, 8, 2, 9, 0}

Here the mode is the number " 2 ". Because it is the number that appear often.

2.{1, 2, 1, 2, 3, 4, 1, 5, 2, 6, 7, 8, 2, 9, 0}

Here, there's around two numbers that are repeating: "1", (around 3 times) "2" (around 4 times). therefor, the mode is number 2. 

3.{1, 2, 1, 2, 3, 4, 1, 5, 2, 6, 7, 8, 1, 2, 9, 0}

Here, there's around two numbers that are repeating: "1", (around 4 times) "2" (around 4 times). therefor, the mode is number 1 and 2. Because both number appears often (Same times). 

KEY-POINTS 

1. Arrange the numbers in ascending order, but if the numbers is to many, you can just skip.

2. Find the numbers that appears most often (Mark them if possible so that you can count them.)
