For example, if the value set is 3, 5, and 12, then you would write: (3 x 5 x 12) = 180. For another example, if you want to find the geometric mean for the set 2 and 18, then write: (2 x 18) = 36.
For example, for the set of 3, 5, and 12, write: ∛(180) ≈ 5. 65. In the second example with a set of 2 and 18, write: √(36) = 6.
For example, say you want to find the geometric mean of the value of an object that increases by 10%, and then falls by 3%. Convert 10% to a decimal and add 1 to it to get 1. 10. Then convert 3% to a decimal and subtract it from 1 to get 0. 97. Use the 2 decimal values to find the geometric mean: √(1. 10 x 0. 97) ≈ 1. 03. Convert the number back to a percent by moving the decimal point 2 places to the right and subtracting 1 from it to find a total of a 3% increase in value.
For example, with a set of 7, 9, and 12, you would type in log(7) + log(9) + log(12) before hitting “=” on your calculator. When you solve the functions, your sum will be about 2. 878521796. You may also calculate each of the logarithms separately before adding the answers together.
In this example, there’s a set of 3 numbers, so type in: 2. 878521796 / 3 ≈ 0. 959507265.
For this example, your calculator will read: 10(0. 959507265) ≈ 9. 11.
