In this one, you’ll understand when to use the T-Test, the different types of T-Test, math behind it, how to determine which test to choose in what situation and why, how to read from the t-tables, example situations and how to apply it in R and Python.
This t-distribution table provides the critical t-values for both one-tailed and two-tailed t-tests, and confidence intervals. Learn how to use this t-table with the information, examples, and illustrations below the table.
Sample Questions. Following are some sample questions for your practice. Question 1: For a two-tailed test with an alpha level of 0.30 and 18 as the sample size, what is the critical value we should compare t to? Solution: We can deduce the following from our problem statement.
