# Gamma Distribution

**Gamma Statistical Distribution**

**General Characteristics**

- The Gamma distribution is a two-parameter family of continuous probability distributions.

- Some statistical distributions are special cases of Gamma distribution including; Erlang distribution, Exponential distribution and Chi-Squared distribution.

**Specific Characteristics**

**Key Measures:
**

Shape & Scale

**Range of values:**

0 < x < ∞

**Mean:**

Mean = Shape * Scale

**Standard Deviation, SD:**

SD = √[Shape * Scale]

**Application**

Gamma distributions can be used; to calculate the time required to complete a task & also to calculate inter-arrival time, as well as time taken between failures.
