Did you know?
WebIn the majority of analyses, an alpha of 0.05 is used as the cutoff for significance. If the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist. If the p-value is larger than 0.05, we cannot conclude that a significant difference exists. WebDec 31, 2024 · Using p < 0.05 is often inappropriate. When undergrad students of data science, economics, or statistics are introduced to statistical inference, they learn how to perform hypothesis testing using a default confidence interval of 0.95. The use of 0.95 — or the equivalent p < 0.05 — is widespread in both teaching, research, and when ...
