Webb12 mars 2024 · The Alpha Level The alpha level of a hypothesis test is the threshold we use to determine whether or not our p-value is low enough to reject the null hypothesis. It is often set at 0.05 but it is sometimes set as low as 0.01 or as high as 0.10. Webb28 aug. 2024 · The p-value (also known as Alpha) is the probability that our Null Hypothesis is true.

Webb15 sep. 2024 · In terms of significance level and power, Weiss says this means we want a small significance level (close to 0) and a large power (close to 1). Having stated a little bit about the concept of power, the authors have found it is most important for students to understand the importance of power as related to sample size when analyzing a study or … 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.
