Question

Which of the following statements correctly describe power? Check all that apply. The power of an experiment is the probability of a Type I error. Power is a value between 0 and 1. Power equals 1/beta (where beta is the probability of a Type II error). Power is a value between 1 and 10. The lower the power, the less sensitive the research study is to detect a real effect or difference. When and why are researchers typically concerned about the power of an experiment? Check all that apply. Researchers are concerned after conducting the experiment when they are trying to figure out why a study failed to find a significant effect. Researchers are concerned before conducting the experiment so that they can design the experiment to maximize power. Researchers are concerned after conducting the experiment so that they can design the experiment to maximize power. Researchers are concerned before conducting the experiment so that they can design the experiment to minimize power. Power values of 0.80 to 1.00 are very very desirable.

Explanation / Answer

Power is a value between 0 and 1

because the power is a probability

for the second multiple question the answer are

both that have maximize power

why? because the reascherers need to see that the power is very big to say that the test that they are doing is very powerfull
