The p-value and critical value are two key pieces of statistical information that can be used to help you understand the results of your research. The p value is a measure of the probability that your results are due to chance, and the critical value is the point at which your results are considered statistically significant. WebThe main difference is that instead of computing a p-value, the classical approach finds critical values. The critical values are the scores which separate the rejection regions from the non-rejection regions, using the numerical scale of the distribution of the test statistic. alinea lincoln park
