KnowraStudent's t-distributionLinked fromLinked fromThe 10 pages that link to Student's t-distribution, each with the reason it gives.All 10Broader topic 2Related 2Narrower topic 1Compared with 5Normal distributionCompared with: It accounts for extra uncertainty when estimating variance from small samples.Cauchy distributionCompared with: With one degree of freedom, Student’s t-distribution is exactly the standard Cauchy distribution.Gaussian distributionCompared with: Its heavier tails better accommodate uncertainty from estimating variance with limited data.Chi-squared distributionCompared with: It uses a chi-squared variable in its construction but describes a signed statistic with heavier tails.F-distributionCompared with: The square of a Student t variable follows an F-distribution with one numerator degree of freedom.
