WebThe best way to calculate it manually is: t.value = (mean (data) - 10) / (sd (data) / sqrt (length (data))) p.value = 2*pt (-abs (t.value), df=length (data)-1) You need the abs () function because otherwise you run the risk of getting p-values bigger than 1 (when the mean of the data is bigger than the given mean)!

WebAug 10, 2024 · The p -value is a number between 0 and 1 and interpreted in the following way: A small p -value (typically ≤ 0.05) indicates strong evidence against the null hypothesis, so you reject the null hypothesis. A large p -value (> 0.05) indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis. WebAboutTranscript. We compare a P-value to a significance level to make a conclusion in a significance test. Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis.
