        However, there are also risks associated with relying on the t-statistic:

        How is the t-statistic calculated in practice?

        t = (x̄1 - x̄2) / (s * sqrt(1/n1 + 1/n2))

        So, what exactly is the t-statistic? Simply put, it's a statistical measure used to determine the significance of the difference between two groups. When comparing the means of two groups, the t-statistic calculates the number of standard errors between the two means. A large t-statistic indicates a significant difference, while a small t-statistic suggests that the difference may be due to chance.
