Two-sample t test

The two-sample t-test is a fundamental statistical method used to compare the means of two independent groups to determine if there is a significant difference between them. It is a powerful tool in various fields, including psychology, biology, and economics, enabling researchers to assess the impact of interventions, treatments, or variables on different populations. By analyzing the means and variances of two samples, the t-test provides valuable insights into whether observed differences are statistically significant or simply due to chance. Understanding its principles and applications is crucial for researchers and practitioners seeking to draw valid conclusions from their data.
