Tweet T-tests are handy hypothesis tests in statistics when you want to compare means. You can compare a sample mean to a hypothesized or target value using a one-sample t-test.

You can compare the means of two groups with a two-sample t-test. If you have two groups with paired observations e.

How do t-tests work? How do t-values fit in? In this post, I will explain t-values, t-distributions, and how t-tests use them to calculate probabilities and assess hypotheses.

T-tests are called t-tests because the test results are all based on t-values. T-values are an example of what statisticians call test statistics.

A test statistic is a standardized value that is calculated from sample data during a hypothesis test. The procedure that calculates the test statistic compares your data to what is expected under the null hypothesis.

Each type of t-test uses a specific procedure to boil all of your sample data down to one value, the t-value. The calculations behind t-values compare your sample mean s to the null hypothesis and incorporates both the sample size and the variability in the data. A t-value of 0 indicates that the sample results exactly equal the null hypothesis.

As the difference between the sample data and the null hypothesis increases, the absolute value of the t-value increases. Assume that we perform a t-test and it calculates a t-value of 2 for our sample data.

What does that even mean? I might as well have told you that our data equal 2 fizbins! We need a larger context in which we can place individual t-values before we can interpret them.

This is where t-distributions come in. When you perform a t-test for a single study, you obtain a single t-value.

However, if we drew multiple random samples of the same size from the same population and performed the same t-test, we would obtain many t-values and we could plot a distribution of all of them. This type of distribution is known as a sampling distribution.

Fortunately, the properties of t-distributions are well understood in statistics, so we can plot them without having to collect many samples! A specific t-distribution is defined by its degrees of freedom DFa value closely related to sample size.

Therefore, different t-distributions exist for every sample size.The t-test, and any statistical test of this sort, consists of three steps. Define the null and alternate hyptheses, Calculate the t-statistic for the data, Compare t calc to the tabulated t-value, for the appropriate significance level and degree of freedom.
