This is because the one-tailed test concentrates the rejection region into one tail, making it easier to achieve statistical significance, provided the effect aligns with the predicted direction. However, this number alone lacks context.
How to Calculate P Value from T Test Statistic Step by Step
This conversion relies entirely on the known sampling distribution of the specific test statistic you are using, such as the z, t, chi-square, or F distribution. Responsible interpretation requires considering the effect size, confidence intervals, and the broader context of the research question alongside the p value.
To determine p value from test statistic , you must assess how extreme that result would be, assuming the null hypothesis is true. Instead, it quantifies the compatibility of your observed data with the null hypothesis.
