T-test
A T-test is a statistical method used to compare the means (averages) of two groups to see if they are significantly different from each other. For example, it can help determine if a new teaching method improves student test scores compared to a traditional method. The T-test considers the size of the groups and the variability in their scores, generating a value (the T statistic) that helps assess if any observed difference is likely due to chance or a true effect. It's commonly used in research to draw conclusions about populations based on sample data.

A t-test is a statistical method used to compare the means of two groups to determine if they are significantly different from each other. For example, it can help us understand if students from two different teaching methods perform differently on a test. By calculating the t-test, we assess whether any observed differences are likely due to chance or reflect a real difference between the groups. It’s commonly used in research to validate hypotheses and draw conclusions about populations based on sample data.
