Question

what do you understand by the term average explain any three mathematical properties of arithmetic mean​

Answer 1

Answer:

Explanation:In statistics, the Arithmetic Mean (AP) or simply called average is the ratio of all observations to the total number of observations. The arithmetic mean can also inform or model concepts outside of statistics. In a physical sense, the arithmetic mean can be thought of as a centre of gravity.

Answer 2

Explanation:

Properties of Arithmetic Mean The sum of deviations of the items from their arithmetic mean is always zero, i.e. ∑(x – X) = 0. The sum of the squared deviations of the items from Arithmetic Mean (A.M) is minimum, which is less than the sum of the squared deviations of the items from any other values.
