Which measure describes the most frequently occurring value in a data set?

Median
Mean
Mode
Standard Deviation

The correct answer is: Mode

The mode is the measure that describes the most frequently occurring value in a data set. It identifies the value that appears most often, making it especially useful in understanding the distribution of categorical data or when dealing with non-numerical variables. In a given data set, if one particular value appears more often than any other, that value is designated as the mode. For example, if a data set consists of the numbers {2, 3, 4, 4, 5}, the number 4 is the mode since it appears more times than any other number. The other measures—median, mean, and standard deviation—serve different statistical functions. The median represents the middle value when a data set is ordered from least to greatest, while the mean calculates the average value. Standard deviation measures the variability or dispersion of the data set. Hence, in the context of identifying the most frequently occurring value, the mode is the correct term to use.
