Math Mode and Range Tutorial.

Mode Definition:

Mode is the most frequently occurring value in a frequency distribution.

Example:

To find the mode of 11,3,5,11,7,3,11

Step 1:

Arrange the numbers in ascending order. 3,3,5,7,11,11,11

Step 2:

In the above distribution Number 11 occurs 3 times, Number 3 occurs 2 times, Number 5 occurs 1 times, Number 7 occurs 1 times. So the number with most occurrances is 11 and is the Mode of this distribution. Mode = 11

Range Definition:

Range is the difference between the highest and the lowest values in a frequency distribution.

Example:

To find the range in 3,5,7,3,11

Step 1:

Arrange the numbers in ascending order. 3,3,5,7,11

Step 2:

In the above distribution The largest number is11 The smallest value is 3 Formula = largest number - smallest number Range = 11-3 = 8
