The sum of a set of values divided by the number of values.

The sum of a set of values divided by the number of values.

• A. Average
• B. Radius
• C. Fraction
• D. Area

Answer: (A)

The concept being tested is the average, found by adding all the values and dividing by how many values there are. This yields a single number that represents a central or typical value in the data. For example, with values 2, 4, and 6, the sum is 12 and there are 3 values, so the average is 12 ÷ 3 = 4. This single value helps summarize the dataset and compare groups. The other terms don’t fit: a radius is a distance in a circle, area is the amount of space inside a shape, and a fraction is a part of a whole expressed as a ratio.
