Which statistical measure represents the value that appears most frequently in a data set?

• A. Mean
• B. Median
• C. Mode
• D. Range

Answer: (C)

The statistical measure that represents the value appearing most frequently in a data set is the mode. The mode indicates the most common data point in a given group of numbers, making it particularly useful for understanding the most typical value in a categorical, nominal, or ordinal set. For example, in the data set {2, 4, 4, 5, 6}, the value '4' appears most frequently, identifying it as the mode. In contrast, the mean is the arithmetic average of all the values, calculated by adding them up and dividing by the total number of values, while the median represents the middle value when data is arranged in ascending order. The range measures the difference between the highest and lowest values in a data set. Each of these measures provides different insights but does not capture frequency in the same way that the mode does.
