Question

explain the following a) geometric mean B) standard deviation c) Skewness​

Answer 1

Geometric mean:

In mathematics, the geometric mean is a mean or average, which indicates the central tendency or typical value of a set of numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum).

Standard devistion:

a quantity expressing by how much the members of a group differ from the mean value for the group.

Skewness:

Skewness is asymmetry in a statistical distribution, in which the curve appears distorted or skewed either to the left or to the right. Skewness can be quantified to define the extent to which a distribution differs from a normal distribution. ... This situation is also called positive skewness.
