The T distribution also known as the Student s t distribution is a type of probability distribution that is similar to the normal distribution with its bell shape but has heavier tails T The F distribution is derived from the Student s t distribution The values of the F distribution are squares of the corresponding values of the t distribution One Way
We only note that Chi square is a class of distribu tion indexed by its degree of freedom like the t distribution In fact chi square has a relation with t We will show this later 2 Mean and In probability theory and statistics Student s t distribution or simply the t distribution is a continuous probability distribution that generalizes the standard normal distribution Like the latter it is symmetric around zero and bell shaped

The t distribution also known as Student s t distribution is a way of describing data that follow a bell curve when plotted on a graph with the greatest number of observations close to the mean and fewer observations in 1 Definition of F distributions relation to t distributions An F distribution with n1 degrees of freedom in the numerator and n2 in the denominator or F n1 n2 is the distribution of U n1
Perhaps the single most important probability distribution involving a continuous r v is the normal distribution Its bell shaped picture as shown in Figure A 3 should be familiar to anyone with A random variable has an F distribution if it can be written as a ratio between a Chi square random variable with degrees of freedom and a Chi square random variable independent of
