What is the average of all scores referred to as?

The average of all scores is referred to as the mean. The mean is calculated by taking the sum of all values and dividing it by the number of values. This provides a central value that represents the overall distribution of the data set. The mean is commonly used in statistics because it incorporates every score in the dataset, which can give a more accurate representation of the overall performance or behavior in scenarios like testing or measurements.

In contrast, the mode refers to the most frequently occurring score in a dataset, while the median is the middle score when all values are arranged in order. Frequent distribution is not a standard term used to describe averages or measures of central tendency. These distinctions clarify why the mean is the correct answer in this context.
