29 kwi 2022 · Student’s t table is also known as the t table, t-distribution table, t-score table, t-value table, or t-test table. A critical value of t defines the threshold for significance for certain statistical tests and the upper and lower bounds of confidence intervals for certain estimates.
Tables T-11. Table entry for p and C is the critical value t∗ with probability p lying to its right and probability C lying between −t∗ and t∗. Probability p.
The t-test is used as an example of the basic principles of statistical inference. One of the simplest situations for which we might design an experiment is the case of a nominal two-level explanatory variable and a quantitative outcome
Using essentially the same procedures we used with the one sample t test, we can calculate the lower limit (LL) and upper limit (UL). Recall, the general formulas for a confidence interval are: LL = (-crit)*(SE) + mean and UL
