Tables T Student

1. The table provides critical values for the Student's t-distribution for various degrees of freedom and significance levels. 2. It shows the t-value cutoffs for one-tailed and two-tailed tests across a range of alpha values from 0.0001 to 0.2 and degrees of freedom from 1 to 200. 3. The critical t-values can be used to determine if a calculated t-statistic is statistically significant or not based on the desired significance level and number of degrees of freedom.
