T test

The t-test is a statistical method used to determine if there is a significant difference between the means of two groups. It is particularly useful when the sample sizes are small and the population standard deviation is unknown. The t-test operates under several assumptions, including the normality of data and independence of observations. There are different types of t-tests, such as independent and paired t-tests, each suited for specific scenarios. By calculating the t-statistic and corresponding p-value, researchers can assess whether the observed differences are statistically significant, helping to draw conclusions about the populations being studied.
