What is the difference between an arithmetic and geometric averages, and what does it tell you about the effect of time on these Nominal Rates?

Expert Solution

Arithmetic Average is calculated by dividing the sum of numbers by the number count. while geometric average takes into account compoundng effect while calculating

Use of Arithemetic average is beneficial in situation when data is not skewed and not dependent on other variables while geometric average is used in situations when there is great variability in the data.

Arithmetic average is relatively easy to calculate while calculation of geometric average involves complex calculations

Geometric average is used to calculate the rate of return on an investment over a period using compounding effect while use of arithmetic average is suitable in a situation where variable are not dependent on each other.

Geometric average is used in finance to calculate rate of return over a period while arithmetic average is not an appropriate tool in calculating rate of return in finance

Arithmetic average of two numbers is always greater than geometric average of the same numbers.

Arithmetic average tells the average rate of the numbers of variables in data and place equal weight to each number in the variable while geometric average tells the rate using the compounding effect i.e giving more weight to early numbers and less weight to numbers occured at last.

Which of the following best describes the differences between the arithmetic mean and geometric mean growth rates? The procedures used to calculate the geometric mean growth rate and arithmetic mean growth rate are somewhat different, but produce the same result. The geometric mean growth rate calculation takes into account changes in the basis, while the arithmetic mean growth rate does not. The arithmetic mean growth rate is preferable to the geometric mean growth rate when calculating rates of return based on changes in stock...
