In a set of data, there can be more than one mode. A set with two modes is bi-modal, a set with three modes is tri-modal, etc. There can also be a data set with no mode.
Example 1:
Find the mode of the set
In the data set, the numbersandeach occur once.
The numberoccurs twice andoccurs three times.
So, the mode of the data set is.
Example 2:
Find the mode of the set
In the data set, the numbersandeach occur once.
The numbersandoccurs twice.
In this case, the data set has two modes, so it is bi-modal.
The modes areand.
