The mode is the value that occurs most frequently in a data set. To find it, see which value appears the most times. For example, in a data set where 4 shows up three times and other numbers show up fewer times, the mode is 4. Keep in mind some data sets can have more than one mode if two or more values share the highest frequency, or no mode if all values occur equally often. Range, by contrast, is the spread between the smallest and largest values and tells you about dispersion, not a single recurring value. Median is the middle value when the data are ordered, giving a central point but not the most frequent value. Central tendency is a broad term for measures like mean, median, and mode, describing the center of the data rather than identifying a specific recurring value.
