![]() There should be no outliers in the sample.The dependent variable needs to be measured on a continuous scale. This follows a few predictions to go with the choice of a variable and design. For a one-sample t-test to provide the user with a valid result, we have to see many approaches that the data must meet. In this post, we’ll look at how to use Minitab to do a one-sample t-test, as well as how to implement and report the given values. ![]() The 2-sample t-test, unlike the paired-samples t, needs distinct groups for every sample. The technique is quite identical to the 1-sample t-test, and the transmission ratio analogy can still be used. Of alcohol related automobile fatalities?ī.The 2-sample t-test reduces the sample data from two groups to a single t-value. Is this sufficient evidence to say that Connecticut has a higher percentage In a random sample of 96 automobile accident fatalities in the state of Connecticut, 44 wereĪlcohol related.
