Below are the ages at which U.S. presidents began their first terms, increasing in order from
George Washington to Barack Obama, with Grover Cleveland serving 2 nonconsecutive terms.
This is an entire population of data, not a sample. This data is in column "Presidents Ages" in the
Minitab worksheet.

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
