Practical Example of GM Calculation
Let’s understand how the tool works with a real example:
Input Numbers:
2, 4, 8, 16
Step 1: Product Calculation
2 × 4 × 8 × 16 = 1024
Step 2: Count of Numbers
There are 4 values
Step 3: Geometric Mean Formula
Geometric Mean =
(1024)^(1/4) = 5.6569
Step 4: Interpretation
- Since the GM value is moderate, the dataset shows balanced growth behavior
