• Incorrect assumptions about the data distribution
  • 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.

    While the t-statistic is often used for comparing means, it can also be used to compare proportions, medians, and other metrics.
