Question: 1 / 400

What value is typically used to represent a mean in a data set?

The median

The average

In a data set, the mean is calculated by summing all the values and then dividing that sum by the total number of values. This calculation gives a measure of central tendency that is commonly referred to as the average. Therefore, the term "average" directly corresponds to the mean and is typically used to represent it.

In contrast, the median represents the middle value when the data set is ordered, the mode indicates the most frequently occurring value in the set, and an outlier is a data point that differs significantly from other observations. Each of these serves different purposes in data analysis but does not define the mean. Thus, the correct understanding of the mean aligns it with the concept of the average.
