Measures of Center - The Mode

The Mode

The mode is the most frequently observed value in our dataset.

There might be multiple modes for a particular dataset, or no mode at all.

No Mode

If all observations in our dataset are observed with the same frequency, there is no mode. If we have the dataset:

1, 1, 2, 2, 3, 3, 4, 4

There is no mode, because all observations occur the same number of times.

Many Modes

If two (or more) numbers share the maximum value, then there is more than one mode. If we have the dataset:

1, 2, 3, 3, 3, 4, 5, 6, 6, 6, 7, 8, 9

There are two modes 3 and 6, because these values share the maximum frequencies at 3 times, while all other values only appear once.
