Key Takeaways. Alpha shows how well (or badly) a stock has performed in comparison to a benchmark index. Beta indicates how volatile a stock's price has been in comparison to the market as a whole. A high alpha is always good.

Alpha decay forms new element with two fewer protons and two fewer neutrons; Beta decay forms new element with one more proton and one fewer neutron. ... Gamma radiation has the highest penetration power, Beta decay goes the second, alpha decay the last.

Beta is calculated using regression analysis. A beta of 1 indicates that the security's price tends to move with the market. A beta greater than 1 indicates that the security's price tends to be more volatile than the market. A beta of less than 1 means it tends to be less volatile than the market.

ALPHA cards are black bordered and have very very rounded edges (2mm radius) compared to all other kinds of magic cards (1mm radius). Just pick up a black bordered card and overlay them on top of each other. If the corners are VERY different then you have ALPHA, otherwise you have BETA.

The alpha factor (α) of a transistor is the ratio of its collector and emitter currents (α = Ic/Ie), and it is always less than 1 (between 0.5 and 1). The beta (β) or current gain is the ratio of its collector and base currents (β = Ic/Ib), and it is always more than 1. The α factor is also calculated as α = β/(β+1) .

Beta Items. Beta: Beta is the testing period of a game. It is used to find bugs and help give feedback about the game. Any items/features released during this time are considered “beta”.

Alpha Testing is a type of software testing performed to identify bugs before releasing the product to real users or to the public. ... Beta Testing is performed by real users of the software application in a real environment. Beta testing is one of the type of User Acceptance Testing.

Gamma particles travel at the speed of light, they are simply E.M radiation. Beta and alpha particles van both travel at any speed. Beta particles tend to travel much faster, however, because they have a much lower mass. beta particles can be sped up and down with a magnetic field, whilst alpha particles can not.

The best I can do is to contend that correlation describes the degree of the relationship between two variables, whereas beta describes the change in volatility (as defined by standard deviation) for a given change in correlation. ... The variables need to be considered together.

Alpha and beta testing are two of the stages that a software must undergo testing. Alpha testing occurs first and when the software passes that, beta testing can then be undertaken. If a software fails alpha testing, changes are done and it repeats the tests until the software passes.

The main difference between alpha and beta carotene is that alpha carotene contains a single retinyl group, whereas beta carotene contains two retinyl groups. ... Alpha carotene and beta carotene are two types of carotene, which are unsaturated hydrocarbon substances exclusively synthesized by plants but, not by animals.

Alpha diversity is the diversity in a single sample site (e.g. human gut) and beta diversity describes the difference in diversity between those sites1 (e.g. different regions of the body). With a variety of alpha and beta diversity indices available, it can be difficult to determine which index to choose.

Alpha levels A one-tailed test has the entire 5% of the alpha level in one tail (in either the left, or the right tail). A two-tailed test splits your alpha level in half (as in the image to the left). Let's say you're working with the standard alpha level of 5%.

Alpha and beta rays are deflected in opposite directions in a magnetic field because they are oppositely charged—alpha are positive and beta negative. Gamma rays have no electric charge and are therefore undeflected.

Essentially, an alpha male is the leader or most dominant man (mentally or physically) in a situation. A beta male is the male below him (or second in command) and an omega male is the lowest ranking male.
