Which measure is defined as the arithmetic average of the scores?

• A. Mean
• B. Mode
• C. Median
• D. Central Tendency

Answer: (A)

The main idea here is how we summarize a set of numbers with a central value, specifically using the arithmetic average. The measure defined as the arithmetic average is the mean, which is calculated by adding all scores and dividing by how many scores there are. This is why it’s described as the average of the data in a sense that every value contributes to the result. This is the best answer because it matches exactly the definition of the arithmetic average. The other terms describe different ideas: the mode is the value that occurs most often, the median is the middle value when the data are ordered, and central tendency is the broad category that includes all such measures. As an illustration, for the numbers 2, 4, 6, 8, 10, the sum is 30 and there are 5 values, so the mean is 6. The mean uses every data point, which is why it’s the appropriate descriptor of the arithmetic average.
