If you have independent samples then you must use two-sample t-test. Remember, this test is also known as independent t-test. However, if your samples are connected then you should use paired t-test.

By Vishal Answered 4 years ago

Paired t-test can be used in the following situations. a) When you need to test two production lines to check if their outputs are different. b) If you want to compare test scores for the same group before as well as after the study.

If you don’t know which test is to be used for your study, take help from the statisticians. They will be aware of all the tests and also know when to use the respective test. http://geoffandfrancis.co.uk/, http://www.dissertationindia.com/.
