P Value Calculator add-in. Normal, t (Student’s t), 2 (chi-squared), F, and Durbin-Watson d distributions are available. The user provides needed input and the add-in calculates the P-Value. The user can obtain a picture of the results for P-Values greater than 0.01% (except for the Durbin Watson d statistic).

When finding the domain of a function, ask yourself what values can't be used. ... Since h(p) is a rational function, the bottom can not equal zero. Set p2 - 4 = 0 and solve: p2 - 4 = 0 ( (p + 2)(p - 2) = 0 ( p = -2 or p = 2. These two p values need to be avoided, so the domain of h(p) is { p | all ... No value of w causes the denominator to ...

Finding the p-value (probability that the result we got or a more extreme one happens just by chance given that the null hypothesis is true). Deciding if the p-value is small or large. In the ducks case we felt like rejecting the null hypothesis because the p-value was small.

These notions are central to the idea of P-value. When you find the z or t value of your sample, it’s natural to wonder how odd such a sample would be, if the null hypothesis were true. The P-value of the sample answers this, by telling you what fraction of all samples would …

This Tip Sheet provides an overview of how to perform the single-sample t test in Excel, which includes calculating the test statistic, finding the appropriate critical value for comparison, and finding the p-value of the computed t statistic. The formula for the single-sample t statistic is shown below.

https://info.5y1.org/finding-p-value-from-t_1_965c83.html
Summary: To find the p-value for the hypothesis test for the difference in means, look in the column labeled “Sig. (2-tailed)” in the “t-test for Equality of Means” section, and in the second row (labeled “Equal variances not assumed”). Note that since the p-value given by SPSS is 2-tailed, you need to divide it in half for a 1-tailed test. In the above example the 1-tailed p-value would be .001.
