Student's t-test

The video tutorial explains the origin and application of the Student's t-test, a statistical method developed by William Sealy Gosset under the pseudonym 'Student'. It covers the conceptual understanding of the t-test, including the calculation of the t-value using spreadsheets, and how to perform a t-test to determine statistical significance between two sample sets. The tutorial also discusses the assumptions required for a t-test and the difference between independent and paired tests, as well as one-tailed and two-tailed tests.
