Type I Error

A Type I error occurs in hypothesis testing when a true null hypothesis is incorrectly rejected, falsely indicating a significant effect or difference when there is none.

Significance Level

The probability of rejecting the null hypothesis in a statistical test when it is actually true, typically denoted as alpha.

P < .01

Indicates that the probability of the observed data occurring by chance is less than 1%, suggesting strong evidence against the null hypothesis.

P < .05

"P < .05" indicates that the probability of the observed data (or something more extreme) given that the null hypothesis is true is less than 5%, commonly used as a threshold for statistical significance.
