Euclidean Distance Score

• It is a simple method to calculate distance between two points in space.

Euclidean Distance Formula

Distance, d = √(x2-x1 )2 + (y2-y1 )2 +(z2-z1)2

How to calculate?

Distance, d = √(x2-x1 )2 + (y2-y1 )2

D(John, Ravi) = √(1.5-4.5 )2 + (4-1.5 )2

= √(3 )2 + (2.5 )2

= 3.91
