Returns the Student's left-tailed t-distribution. The t-distribution is used in the hypothesis testing of small sample data sets. Use this function in place of a table of critical values for the t-distribution.
The guide explains how to install the data analysis toolpak and provides the excel syntax for six type of T Distribution functions, namely: Left-tail T Distribution, Right-tail T Distribution, One-Tail T Distribution, Two-Tail T Distribution, Left-tailed Inverse of Student t-distribution and Two-tailed Inverse of Student t-distribution.
The T.DIST Function will calculate the T distribution. The T distribution is a continuous probability distribution that is frequently used in testing hypotheses on small sample data sets. Learn the T Distribution Excel function and the T Value Excel function in this guide with formulas and examples.
The t distribution provides a good way to perform one-sample tests on the mean when the population variance is not known provided the population is normal or the sample is sufficiently large so that the Central Limit Theorem applies (see Properties 1 and 2 of Basic Concepts of t Distribution).
The Student’s t Distribution and the corresponding t-tests play an important role in hypothesis testing of the mean. We review the key properties of the t distribution and how to perform the various t-tests in Excel, along with how to handle situations where some of the sample data is missing.
T.DIST Function returns the student t distribution for the left tailed test using the variable x and deg of freedom along with the type of distribution (cdf or pdf) T.DIST Function syntax: =T.DIST(x , deg_freedom ,tails)
