About Entropy Calculator

Welcome to our Entropy Calculator, a user-friendly tool designed to calculate the Shannon entropy of a discrete probability distribution. Entropy measures the unpredictability or average information content within a set of outcomes.

Features of the Entropy Calculator

Understanding Entropy

For a discrete random variable \( X \) with possible outcomes \( x_i \) and corresponding probabilities \( p_i \), the Shannon entropy is given by:

\[ H(X) = - \sum_{i} p_i \log\bigl(p_i\bigr) \]

This measures the average level of “surprise” or uncertainty in the distribution.
