A common mistake is to treat a statistically significant result as proof of a real effect. Common Misconceptions and Pitfalls It is crucial to remember that the p value is not the probability that the null hypothesis is true.

Test Statistic Type Distribution Used Primary Use Case z-score Standard Normal Large samples, known population variance t-score t-Distribution Small samples, unknown population variance Chi-square Chi-square Distribution Goodness-of-fit, independence tests F-statistic F-Distribution Analysis of variance (ANOVA) Interpreting Direction and Complexity The directionality of your hypothesis directly impacts how you determine p value from test statistic. Instead, it quantifies the compatibility of your observed data with the null hypothesis.
To determine p value from test statistic , you must assess how extreme that result would be, assuming the null hypothesis is true. 051 is not fundamentally different from 0.

For a one-tailed test, you focus on only one tail, depending on the direction of your alternative hypothesis. Understanding how to determine p value from test statistic is fundamental for interpreting the results of any statistical analysis.
