What is the T Distribution? The T distribution (also called Student’s T Distribution) is a family of distributions that look almost identical to the normal distribution curve, only a bit shorter and fatter. The t distribution is used instead of the normal distribution when you have small samples (for more on this, see: t-score vs. z-score). What is a t-distribution? The t -distribution is a way of describing a set of observations where most observations fall close to the mean, and the rest of the observations make up the tails on either side. It is a type of normal distribution used for smaller sample sizes, where the variance in the data is unknown.

1999-08-10 · The t-distribution. Suppose a researcher at State University wants to know how satisfied students are with dormitory living. The researcher administers a survey where students answer questions on a scale of 1 to 7 with 1 representing very unsatisfied with dormitory living and 7 representing very satisfied with dormitory living. The t distribution appears to complete various statistical tests to estimate unknown parameters (such as standard deviation of the population).

z-score ).

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. Syntax. T.DIST(x,deg_freedom, cumulative) The T.DIST function syntax has the following arguments: X Required.

The t- distribution describes the standardized distances of sample means to the population mean when the population standard deviation is not known, and the observations come from a normally distributed population. Is the t- distribution the same as the Student’s t -distribution? In a testing context, the tdistribution is treated as a "standardized distribution" (i.e., no location or scale parameters).

In a testing context, the t distribution is treated as a "standardized distribution" (i.e., no location or scale parameters). However, in a distributional modeling context (as with other probability distributions), the t distribution itself can be transformed with a location parameter, μ, and a scale parameter, σ.

The t- distribution is most useful for small sample sizes, when the population standard deviation is not known, or both. As the sample size increases, the t- distribution becomes more similar to a normal distribution. A specific t-distribution is defined by its degrees of freedom (DF), a value closely related to sample size.
