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. WebThis table contains critical values of the Student's t distribution computed using the cumulative distribution function. The t distribution is symmetric so that t 1-α,ν = -t α,ν.
