**What is critical value in t-distribution?**

A critical value is a point on the distribution of the test statistic under the null hypothesis that defines a set of values that call for rejecting the null hypothesis. This set is called critical or rejection region. Usually, one-sided tests have one critical value and two-sided test have two critical values.

### How do you use the t-distribution table of values?

To use the t-distribution table, you only need to know three values:

- The degrees of freedom of the t-test.
- The number of tails of the t-test (one-tailed or two-tailed)
- The alpha level of the t-test (common choices are 0.01, 0.05, and 0.10)

### What is the difference between T distribution and normal distribution?

The normal distribution assumes that the population standard deviation is known. The t-distribution is defined by the degrees of freedom. These are related to the sample size. The t-distribution is most useful for small sample sizes, when the population standard deviation is not known, or both.
