What do you call the most frequent value in a set of data?

The most frequent value in a set of data is known as the mode. The mode represents the number or item that appears most often within a given data set, highlighting its prominence compared to other values. In contrast, the mean is the average of all values, calculated by adding them together and dividing by the total number. The median is the middle value when the data set is organized in ascending or descending order, effectively dividing the data into two equal halves. Standard deviation measures the amount of variation or dispersion in a set of values. Therefore, mode specifically refers to the frequency of occurrence, making it the correct answer in this context.
