The t distribution calculator accepts two kinds of random variables as input: a t score or a sample mean. Choose the option that is easiest. Here are some things to consider. If you choose to work with t statistics, you may need to transform your raw data into a t statistic. This is an online T-distribution Calculator. The shape of the Student's t-distribution is determined by the degrees of freedom. Its shape changes as the degrees increase Instructions: Use this T-Distribution Probability Calculator to Compute t-distribution probabilities using the form below. Please type the number of degrees of freedom associated to the t-distribution, and provide details about the event you want to compute the probability for: Student T Inverse Cumulative Distribution Function Calculator: Just enter the degrees of freedom and select the confidence interval among the 99% or 95% or 90% and click on calculate, the online Inverse T Distribution calculator will display you the results within the fractions of seconds. T Distribution: It is also called Student's t-distribution which is used in the population parameters
