What happens to the mode of the data set (4, 3, 6, 7, 8, 9, 12,) when the number 5 is added?

Hi!

The mode is the number in a data set that repeats the most. 
3, 4, 6, 7, 8, 9, 12
There is no mode in this data set. 

Add 5.
3, 4, 5, 6, 7, 8, 9, 12
There is still no mode. 

The answer is B. The mode is not changed

Hope this helps! :)
