Calculating the degrees of freedom, df= 10 - 1= 9. This gives us a p-value of .95. However, since this is right-tail hypothesis testing, to calculate the actual p-value, we must take 1 and subtract this from .95, which gives us a value of .025.

A simple calculator that generates a P Value from a Pearson (r) score.

Free web calculator provided by GraphPad Software. Calculates the P value from z, t, r, F, or chi-square.

P Value from Pearson (R) Calculator This should be self-explanatory, but just in case it's not: your r score goes in the R Score box, the number of pairs in your sample goes in the N box (you must have at least 3 pairs), then you select your significance level and press the button.

Aug 06, 2020 · To find this two-tailed p-value we simply multiplied the one-tailed p-value by two. The p-value is 0.2149. If we use a significance level of α = 0.05, we would fail to reject the null hypothesis of our hypothesis test because this p-value is not less than 0.05. Related: You can also use this online Z Score to P Value Calculator to find p-values.

Aug 06, 2020 · Suppose we want to find the p-value associated with a t-score of 1.87 and df = 24 in a right-tailed hypothesis test. #find p-value pt (q=1.87, df=24, lower.tail=FALSE) [1] 0.03686533. The p-value is 0.0368. If we use a significance level of α = 0.05, we would reject the null hypothesis of our hypothesis test because this p-value is less than 0.05.

So we calculate the sample mean and sample standard deviation in order to calculate the p value: > t <- (mean( w1 $ vals)-0.7)/( sd ( w1 $ vals)/sqrt(length( w1 $ vals ))) > t [1] 1.263217 > 2* pt (-abs(t), df =length( w1 $ vals)-1) [1] 0.21204 10.3. Calculating Many p Values From a t Distribution

To calculate the p-value, this calculator needs 4 pieces of data: the test statistic, the sample size, the hypothesis testing type (left tail, right tail, or two-tail), and the significance level (α). When you're working with data, the numbers of the data itself is not very meaningful, because it's not standardized.
