Arithmetic average of a set of values.

The correct answer is D. Mean. Mean (D) is the arithmetic average - calculated by summing all values in a set and dividing by the count of values (e.g., the mean of 2, 4, 6 is 12÷3 = 4). The median (A) is the middle value when data is sorted, not an average calculation. A sample (B) is a subset of a…

Explanation

Mean (D) is the arithmetic average - calculated by summing all values in a set and dividing by the count of values (e.g., the mean of 2, 4, 6 is 12÷3 = 4). The median (A) is the middle value when data is sorted, not an average calculation. A sample (B) is a subset of a population used for data collection - it's a data source, not a statistical measure. The mode (C) is the most frequently occurring value in a dataset, not an average. Memory tip: Think "mean = math" - it's the only measure that requires actual arithmetic operations on every value in the set.
