The distribution for this example is bimodal, with a major mode corresponding to the modal-class interval to centimetres and a minor mode corresponding to the modal-class interval 80 to 99 centimetres.

The information is grouped by Number of points scored appearing as row headers , Frequency number of games appearing as column headers.
Number of points scored Frequency number of games 0 1 1 1 4 1 5 4 7 2 8 1 0 true zero or a value rounded to zero. Number of points scored Frequency number of games 14 5 15 1 16 5 18 1. The information is grouped by Rank appearing as row headers , Number of touchdowns appearing as column headers. The information is grouped by Number of touchdowns appearing as row headers , Frequency appearing as column headers. Number of touchdowns Frequency 0 6 1 4 2 2 3 2 0 true zero or a value rounded to zero.
The information is grouped by Height in centimetres appearing as row headers , Frequency number of people appearing as column headers. Height in centimetres Frequency number of people 20 to 39 42 40 to 59 60 to 79 80 to 99 to to to to to to This means that this value is the average value, the middle value, also the mode—the most frequently occurring value in the data. Mode is most useful as a measure of central tendency when examining categorical data, such as models of cars or flavors of soda, for which a mathematical average median value based on ordering can not be calculated.
For example, in the following list of numbers, 16 is the mode since it appears more times in the set than any other number:. A set of numbers can have more than one mode this is known as bimodal if there are two modes if there are multiple numbers that occur with equal frequency, and more times than the others in the set. In the above example, both the number 3 and the number 16 are modes as they each occur three times and no other number occurs more often.
If no number in a set of numbers occurs more than once, that set has no mode:. A set of numbers with two modes is bimodal , a set of numbers with three modes is trimodal , and any set of numbers with more than one mode is multimodal. When scientists or statisticians talk about the modal observation, they are referring to the most common observation.

We can try groups of 2 values 4 and 7 2 values 11 and 16 4 values 20, 22, 25 and 26 1 value 33 In groups of 10, the "20s" appear most often, so we could choose 25 the middle of the 20s group as the mode.
You could use different groupings and get a different answer. Example: How long to fill a pallet?
