T.DIST.RT
TheT.DIST.RT
function returns the righttailed Student's tdistribution of a given value, given the degrees of freedom. It is commonly used in hypothesis testing to determine the probability of observing a value as extreme or more extreme than a test statistic under the null hypothesis.

Examples
Here are a few example use cases that explain how to use theT.DIST.RT
formula in Google Sheets.
Testing for significance
The T.DIST.RT function can be used to calculate the pvalue for a onesample ttest or a paired ttest in order to determine if the results are statistically significant.
Quality control
In quality control applications, the T.DIST.RT function can be used to calculate the probability of observing a sample mean that is more extreme than a given value, which can help identify potential issues in a manufacturing process.
Investment analysis
The T.DIST.RT function can be used in investment analysis to calculate the probability of a portfolio's returns falling below a certain threshold, which can help investors manage risk.
Common Mistakes

Google Sheets Formula:
Not using the right degrees of freedom
Make sure you are using the correct degrees of freedom for your situation, as using the wrong degrees of freedom can significantly affect the results of the calculation.
Not understanding the output value
Remember that T.DIST.RT
returns the righttailed probability, so you may need to subtract the result from 1 to get the lefttailed probability or use a different formula entirely if you need a twotailed probability.
Related Formulas
The following functions are similar to T.DIST.RT
or are often used with it in a formula:

T.DIST
The
T.DIST
function returns the probability of a Student's tdistribution with a specified degrees of freedom. This function is usually used in hypothesis testing to determine the probability that a sample mean is within a specified range of values. 
T.DIST.2T
The
T.DIST.2T
function returns the twotailed probability of the Student's tdistribution. This function is commonly used in hypothesis testing to determine if two sets of data have different means. It is also used in confidence interval estimation, where it calculates the probability that the difference between two population means falls within a specified range. 
T.INV
The
T.INV
function returns the inverse of the Student's tdistribution for the provided probability and degrees of freedom. This function is commonly used to calculate a critical value from the tdistribution when working with small sample sizes. 
T.TEST
The
T.TEST
function calculates the probability associated with a Student's ttest. This function is commonly used in statistics to determine whether two samples are likely to have come from the same two underlying populations that have the same mean. It returns the probability that the two samples are different. The function assumes that the two samples are independent of each other and have equal variances.
