Answer 1

The correct answer is Mean.

Step-by-step explanation:

The correct answer is A. Mean. The arithmetical average of a number of observations is called the mean. It is calculated by summing up all the observations and dividing the sum by the number of observations. For example, if you have a set of numbers {2, 4, 6, 8, 10}, the mean would be (2 + 4 + 6 + 8 + 10)/5 = 6.
