🧮 Mathematical Formulas
All Pairs Method
\[ \text{AvgSqDist} = \frac{1}{n(n-1)} \sum_{i=1}^{n} \sum_{j=i+1}^{n} (x_i-x_j)^2 + (y_i-y_j)^2 + (z_i-z_j)^2 \]
Where n is the number of points, and (x,y,z) are coordinates.
Centroid Method
\[ \text{AvgSqDist} = \frac{1}{n} \sum_{i=1}^{n} \left[(x_i-\bar{x})^2 + (y_i-\bar{y})^2 + (z_i-\bar{z})^2\right] \]
Where \((\bar{x}, \bar{y}, \bar{z})\) is the centroid (mean) of all points.
Note: This calculator provides precise mathematical calculations based on the input points. For statistical applications, ensure your data meets the assumptions of your analysis method.
