Student's t Test and its applications: Dr Surbhi #biostatistics #psychiatry

Student's t-test (also known as Student's t-test) is one of the most widely used parametric statistical tests in research, especially in fields like medicine, psychiatry, psychology, and clinical studies. Developed by William Sealy Gosset (publishing under the pseudonym "Student" in 1908 while working at Guinness Brewery), it helps determine whether there is a statistically significant difference between the means of one or two groups when the population standard deviation is unknown and sample sizes are often small to moderate. It relies on the t-distribution, which accounts for extra uncertainty in small samples (heavier tails than the normal distribution) and approaches the normal distribution as sample size increases (thanks to the Central Limit Theorem). #biostatistics #psychiatry #StudentsTTest #statisticalanalysis #DrSurbhi #datascience #mentalhealthresearch #statisticalmethods #ResearchApplications #quantitativeresearch #PsychometricEvaluation #ClinicalStatistics #DataInterpretation #researchmethods #StatisticalSignificance #PsychiatricStudies #academicresearch #evidencebasedmedicine #StatisticalTools #HealthDataAnalysis
