Fine-Structure Constant
$\alpha$
The symbol for the fine-structure constant is $\alpha$.

Producer's Risk
$\alpha$
Producer's risk is the probability that a consumer rejects a batch with a small number of defectives which would in fact be acceptable to that consumer.
The producer's risk can be denoted by the symbol $\alpha$ (alpha).

Right Ascension
- $\alpha$
Used to denote the right ascension of a point on the celestial sphere.
Let $P$ be a point on the celestial sphere.
The right ascension of $P$ is the angular distance measured eastwards along the celestial equator from the vernal equinox

Significance Level
- $\alpha$
Used to denote the significance level of a hypothesis test.
Let $\delta$ be a hypothesis test.
Let $H_0$ and $H_1$ be the null hypothesis and alternative hypothesis of $\delta$ respectively.
Let $T$ be the test statistic which is being used to determine whether $H_0$ or $H_1$ holds.
Let $C$ be the critical region of $\delta$.
Let $\alpha$ be the probability that $T$ takes a value in $C$ when in fact $H_0$ holds.
$\alpha$ is known as the significance level of $\delta$.
The $\LaTeX$ code for \(\alpha\) is \alpha .
