Web7 aug. 2024 · There are three steps to find the critical value. Choose your alpha (α) value. The alpha value is the probability threshold for statistical significance. The most common alpha value is p = 0.05, but 0.1, 0.01, and even 0.001 are sometimes used. It’s best to look at the research papers published in your field to decide which alpha value to use. Webthe 95% CI does not contain the value 0, then the p-value will be strictly less than 0.05. The same applies when comparing groups using a ratio, such as an odds ratio or risk ratio.
