• The most common value(s) if more than one value repeats in the data
• If no values repeats in the data, there is no mode
• If two values repeats as often, there can be more than one mode

Finding the mode (just one mode)

Example 3.1.1

Find the mode of the following numbers: 19, 20, 21, 21, 21, 23, 24, 24, 27

Step 1: Find the repeating value(s): 19, 20, 21, 21, 21, 23, 24, 24, 27

Step 2: Determine the value(s) that repeat the most: 21

Conclusion: The mode for the above data set is 21.

Finding the mode (Multiple modeS)

Example 3.1.2

Find the mode of the following numbers: 19, 20, 21, 21, 23, 24, 24, 27

Step 1: Find the repeating value(s): 19, 20, 21, 21, 23, 24, 24, 27

Step 2: Determine the value(s) that repeat the most: 21 & 24

Conclusion: The modes for the above data set are 21 and 24.

Finding the mode (No Mode)

Example 3.1.3

Find the mode of the following numbers: 19, 20, 21, 23, 24, 27

Step 1: Find the repeating value(s): there are no repeating values

Step 2: Determine the value(s) that repeat the most: N/A

Conclusion: There is no mode for the above data set.
