WebThe truncated t-table below shows the critical t-value. The t-table indicates that the critical values for our test are -2.086 and +2.086. Use both the positive and negative values for a two-sided test. Your results are statistically significant if your t-value is less than the negative value or greater than the positive value. WebP -value. The p -value (or probability value) is the probability that the test statistic equals the observed value or a more extreme value under the assumption that the null hypothesis is true. The p-value is a probability statement based on the alternative hypothesis.
