What is Power calculation: Definition and 55 Discussions

The power of a binary hypothesis test is denoted by "(1−β)" and is the probability of a "true positive" conditional on a positive outcome. It is the probability that the test correctly rejects the null hypothesis (




H

0




{\displaystyle H_{0}}
) when a specific alternative hypothesis (




H

1




{\displaystyle H_{1}}
) is true. The statistical power ranges from 0 to 1, and as statistical power increases, the size of "β" - the probability of making a type II error by wrongly failing to reject the null hypothesis - decreases.

    When is power constant in this scenario?

    Power P = F x v,where F is force and v is velocity, if power remains constant then i think force can not remain constant as it will change the velocity v, but the solution I found is, F = ma, v = at, so, P = F x v = ma x at = ma2 t, after that calculus comes to show that displacement is...
