WebMar 6, 2024 · A p-value, or probability value, is a number describing how likely it is that your data would have occurred by random chance (i.e. that the null hypothesis is true). The level of statistical significance is often expressed as a p -value between 0 and 1. The smaller the p-value, the stronger the evidence that you should reject the null ... WebThe value -t( α /2, n - 1) is the t -value such that the probability to the left of it is α /2, and the value t( α /2, n - 1) is the t -value such that the probability to the right of it is α /2. It can be shown using either statistical software or a t -table that the critical value -t0.025,14 is -2.1448 and the critical value t0.025,14 is 2.1448.
