What is the Mode?

The mode is the most common (or the data point that appears most often) in a set of data.

It can be found by putting the data into an ordered list and seeing which data point occurs most often.

How to find the mode

Step 1) Put the data into an ordered list.

Step 2) Check that you have got the same number of data points.

Step 3) The mode is the data point which is the most common.

Finding the Mode Examples

Example 1) Find the mode of 3, 6, 4, 3, 2, 4, 7, 8, 6, 3, 9

Step 1) Put the data into an ordered list.

This gives us: 2, 3, 3, 3, 4, 4, 6, 6, 7, 8, 9

Step 2) Check the number of data points in both lists is the same.

Both lists have 11 data points.

Step 3) The mode is the number which occurs most often.

Answer: the mode is 3.

Example 2) Find the mode of 0.6, 0.3, 0.4, 0.2, 0.4, 0.7, 0.6, 0.1, 0.4, 0.9

Step 1) Put the data into an ordered list.

This gives us: 0.1, 0.2, 0.3, 0.4, 0.4, 0.4, 0.6, 0.6, 0.7, 0.9

Step 2) Check the number of data points in both lists is the same.

Both lists have 10 data points.

Step 3) The mode is the number which occurs most often.

Answer: the mode is 0.4.

What is the Range?

The range is the gap between the smallest and largest data point.

It is found by putting the data into an ordered list and find the difference between the largest and smallest amount.

How to find the range

Step 1) Put the data into an ordered list.

Step 2) Check that you have got the same number of data points.

Step 3) The range is the difference between the largest and smallest data point.

To find the range simply subtract the smallest number from the largest number.

Finding the Range Examples

Example 1) Find the range of 14, 21, 9, 32, 27, 15, 12, 30

Step 1) Put the data into an ordered list.

This gives us: 9, 12, 14, 15, 21, 27, 30, 32

Step 2) Check the number of data points in both lists is the same.

Both lists have 8 data points.

Step 3) The range is the difference or gap between the largest and smallest numbers.

Answer: the range is 32-9=23.

Example 2) Find the range of 6, 2, -7, 2, -5, 11, 3, -4, 0, 9

Step 1) Put the data into an ordered list.

This gives us: -7, -5, -4, 0, 2, 2, 3, 6, 9, 11

Step 2) Check the number of data points in both lists is the same.

Both lists have 10 data points.

Step 3) The range is the difference or gap between the largest and smallest numbers.

Answer: the range is 11-(-7)=18.
