Triangular Distribution Variance Calculator

Triangular Distribution Variance Calculator

Calculate the variance of a Triangular distribution defined by minimum \( a \), mode \( c \), and maximum \( b \): $$ \sigma^2 = \frac{a^2 + b^2 + c^2 – ab – ac – bc}{18}. $$

* Enter values such that \( a \le c \le b \).

Step 1: Enter Parameters

e.g., 0

e.g., 5 (must satisfy \( a \le c \le b \))

e.g., 10

Formula: $$ \sigma^2 = \frac{a^2 + b^2 + c^2 – ab – ac – bc}{18}. $$
