T distribution table

T-test calculator is an online statistical tool that performs t-tests for one and two-sample data.

T-value interpretation

Our student t test calculator calculates critical values for selections of data: “Group data”, “Mean, SEM, & N”, and “Mean, SD,& N”. 

This t statistic calculator finds the t-statistics value and compares with the t-critical value to show whether the data is significant or not for experiment.

Our paired t-test calculator performs tests with detailed steps by using unpaired test statistics formula (for equal variances) and Welch’s formula (for unequal variances). 

What is a T Test?

T test is a statistical technique that is used to measure the difference between the mean values of one and two sample datasets by using hypothesis testing.

It is also known as the student’s t-test and is used when data has a normal distribution & unknown variances.

T-test is performed based on the group data values for one-group and two-group data. The t-test uses t-statistic, t-distribution valu
