Main Video: https://youtu.be/E77PYuEEbr4 Student’s t-test (often just called the t-test) is a classical statistical hypothesis test used to compare means when the population standard deviation is unknown and the sample size is relatively small. It was developed by William Sealy Gosset (who published under the pseudonym “Student”) while working at the Guinness brewery in the early 1900s. The test relies on the Student’s t-distribution, which accounts for the extra uncertainty that comes from estimating the standard deviation from the sample itself. #StudentsTTest #statisticalanalysis #hypothesistesting #datascience #ResearchMethods #StatisticsEducation #quantitativeresearch #academicresearch #StatisticalSignificance #experimentaldesign
