In a data set, which measure indicates the most frequent value?

The mode is the measure that indicates the most frequent value in a data set. When analyzing a set of numbers, the mode represents the value that appears with the highest frequency, which can be particularly useful in understanding the distribution of data points, especially in cases where data may be skewed or vary widely.

In contrast, the mean calculates the average of the data set by summing all the values and dividing by the number of values; while the median represents the middle value when the data is arranged in order, providing a measure of central tendency that is less influenced by outliers. The range simply reflects the difference between the highest and lowest values in the data set, providing insight into the spread of the data rather than its frequency. Thus, in the context of identifying the most common value, the mode is the appropriate measure to use.
