Significance level (risk rate)
危険率きけんりつTerm: Significance level (risk rate)
Explanation: The significance level (危険率, kikenritsu) is the probability of wrongly rejecting a scientific hypothesis when that hypothesis is in fact true. It is an important indicator when evaluating the results of statistical analyses or experiments, and is used especially in the context of hypothesis testing in medicine and psychology. A high significance level means a higher risk that a hypothesis will be rejected even though it is true, which affects the reliability of research results.
