WebJun 9, 2024 · The student’s t-distribution (t-distribution) is a probability distribution used for statistical testing with relatively small sample conditions. The t distribution appears to complete various statistical tests to estimate unknown parameters (such as standard deviation of the population).

WebThe T distribution formula is also known as the Student's T Distribution. It is used for estimating the mean of a normally distributed population in those cases when the sample size is limited and the population standard deviation is unknown.
