A paired t-test is a statistical method used to compare the means of two related groups to determine if there is a significant difference between them. This test is particularly useful in scenarios where the same subjects are measured under different conditions or at different times, making the data points dependent on each other. Understanding this test connects to various statistical distributions, sampling methods for means and proportions, and applications in fields like machine learning and data science.
