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.
Collect the data and calculate the t-statistic based on the two sample means, standard deviations, and sample sizes. Compare the calculated t-statistic to the critical value from the t-distribution table to determine whether to accept or reject the null hypothesis.
