# Negative Exponential Distribution

**Negative Exponential Statistical Distribution**

**General Characteristics**

- The Negative Exponential distribution has an inverted curve from the y-axis to the x-axis.

- Unlike Gamma distribution which involves two parameters, the Negative Exponential distribution involves only one parameter, and is thus easier to handle compared to the aforementioned.

**Specific Characteristics**

**Key Measures:
**

Mean

**Range of values:**

0 < x < ∞

**Mean:**

Mean = mean

**Standard Deviation, SD:**

SD = mean

**Application**

Negative Exponential distributions are used in a wide variety of operations, including but not limited to; calculating the time required to complete a certain task, calculating inter-arrival time & calculating the time between failures.
