Which operation calculates the central tendency by adding values and dividing by how many values?

Which operation calculates the central tendency by adding values and dividing by how many values?

• A. Finding maximum
• B. Finding average
• C. Substring
• D. Length

Answer: (B)

This is about the mean, which is a way to describe a dataset by a central value. The operation described—summing all the values and then dividing by how many values there are—calculates the mean, commonly called the average. It gives a single number that represents the middle point of the data. For example, with values 2, 4, 6, and 8, the result is (2+4+6+8)/4 = 5. The other options don’t do this: finding the maximum selects the largest value, substring extracts a part of a string, and length counts how many items or characters are present.
