Webb11 apr. 2024 · It is a type of inferential statistic used to study if there is a statistical difference between two groups. Mathematically, it establishes the problem by assuming that the means of the two distributions are equal (H₀: µ₁=µ₂). If the t-test rejects the null hypothesis (H₀: µ₁=µ₂), it indicates that the groups are highly probably different.
