Mathematically, a T-score is obtained from its corresponding Z-score using the following formula: T=50+10ZT = 50 + 10ZT=50+10Z T-Score Example What is the T-score associated to a z-score ofZ=2.5Z = 2.5Z=2.5? Using the formula above, we find that ...

The formula for a Student’s t-test is: t=xˉ1−xˉ2sp⋅1n1+1n2t=\frac{\bar{x}_{1}-\bar{x}_{2}}{s_{p} \cdot \sqrt{\frac{1}{n_{1}}+\frac{1}{n_{2}}}t=sp⋅n11+n21xˉ1−xˉ2 Given...
Z-score? If you are also interested in F-test, check our F-statistic calculator. What is t-statistic and Student's t-test? In statistics, the t-statistic, or t-value, is a measure that describes the relationship between a sample and its population. The t-statistic is central to the ...
Use the t critical value calculator to find the critical value of t, f, & chi-square if you don’t know how to find critical value.
In most cases, this will mean deciding whether to use z, the familiar z-score associated with the Standard Normal Distribution, or t, the equivalent measure using the Student T-Distribution. These two tests are fairly similar in their execution, particularly when using a calculator, and so it...
For most T-distribution questions, you’ll usually be given all of the information you need to plug into thecalculator and retrieve the T score. You might be asked to find the area under a T curve, or (like Z scores), you might be given a certain area and asked to find the T scor...
