Which statement defines the mode in statistics?

The average value across data The value that appears most frequently in a data set The median value The range

Correct Answer:

The value that appears most frequently in a data set

Explanation:

Mode is the value that appears most frequently in a data set. This focuses on how often a value occurs rather than on balancing or ordering the data. The mean is the average of all values, the median is the middle value when the data are arranged, and the range measures how spread out the data are (largest minus smallest). Sometimes more than one value can occur with the same highest frequency, giving multiple modes. For example, in the set 2, 5, 3, 5, 1, 5, 2, the number 5 shows up most often, so it is the mode.
