For example, for two portfolios, A and B, whose performance differs from the S&P 500 with p-values of 0.10 and 0.01, respectively, the investor can be much more confident that portfolio B, with a ...

However, if your p-value is 0.07 and your significance level is 0.05, you cannot reject the null hypothesis and you have to accept that there is no evidence of a difference or effect. Add your ...

Before we attempt to illustrate how to calculate the P-value of a null hypothesis, let's first look at the definition of a P-value. A P-value is the amount of marginal significance of a statistical ...

The p-value is one of the most important concepts in statistics.When working on research projects, this is the output data scientists often use to find the statistical significance of two data sets.

We have shown in a previous Statistics Note 1 how we can calculate a confidence interval (CI) from a P value. Some published articles report confidence intervals, but do not give corresponding P ...

Typically, if the p-value is small (often set at less than 0.05), it indicates that there is significant evidence against the null hypothesis, which leads to its rejection. On the other hand, larger p ...
