Which statistical measure is defined as the value that occurs the most in a data set?

• A. Mean
• B. Median
• C. Mode
• D. Standard deviation

Answer: (C)

The mode is the statistical measure that represents the value that occurs most frequently in a given data set. It is particularly useful in understanding the most common or popular item within the data. For example, if you have a list of survey results showing people's favorite fruits and 'apple' appears most often, then 'apple' is the mode. This measure can be especially beneficial when working with categorical data, where you want to know the most common category. Unlike the mean, which calculates the average of a data set, or the median, which determines the middle value when the data is ordered, the mode simply focuses on frequency without concern for the order or value of other data points. Additionally, the standard deviation measures the variation or spread of a set of values rather than identifying any single value that appears most frequently. Thus, the mode effectively highlights the most prevalent element in various contexts.
