write what is average with its formula.
Answers
Answer:
There are several kinds of mean in mathematics, especially in statistics. For a data set, the arithmetic mean, also known as arithmetic average, is a central value of a finite set of numbers: specifically, the sum of the values divided by the number of values.
Step-by-step explanation:
Average, which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5. Average equals the sum of a set of numbers divided by the count which is the number of the values being added. For example, say you want the average of 13, 54, 88, 27 and 104. Find the sum of the numbers: 13 + 54 + 88+ 27 + 104 = 286. There are five numbers in our data set, so divide 286 by 5 to get 57.2.
