  • T-tests are parametric tests of difference.
  • T-tests can be related or unrelated.
  • T-tests that are related use the same participants in each condition (like a repeated measures design).
  • T-tests that are unrelated use different participants in each condition (like an independent groups design).
  • The related T-test is a parametric statistical test of difference that allows psychologists to assess significance.
  • A related T-test is used in studies with a repeated measures or a matched pairs design, where the data meets the requirements for a parametric test.
  • The unrelated t-test is a parametric statistical test of difference that allows a researcher to determine the significance of their findings.
  • The unrelated T-test is used in studies that have an independent groups design, where the data meets the requirements for a parametric test.
  • T-tests use data that has an interval level of measurement.
  • A related T-test is used when the same participants are measured under different conditions, while an unrelated T-test is used when different participants are measured under different conditions.
