Critical value of t
WebTo determine whether to reject the null hypothesis using the t-value, compare the t-value to the critical value. The critical value is t α/2, n–p-1, where α is the significance level, n is the number of observations in your sample, and p is the number of predictors.. If the absolute value of the t-value is greater than the critical value, you reject the null … WebAug 28, 2024 · The t-score which generates a p-value below your threshold for statistical significance is known as the critical value of t, or t*. …

WebA critical value defines regions in the sampling distribution of a test statistic. These values play a role in both hypothesis tests and confidence intervals. In hypothesis tests, critical values determine whether the results are statistically significant. For confidence intervals, they help calculate the upper and lower limits.
