Written by The T.DIST.2T function in Excel is a statistical function that calculates the two-tailed Student’s t-distribution. This function is particularly useful in hypothesis testing, providing the probability that a value from a t-distribution will fall within the positive and negative range defined by a given t-statistic. It takes three parameters: the t-statistic, degrees of freedom, and an optional cumulative option, making it straightforward for users to implement in various statistical analyses.
The T.DIST.RT function in Excel is an essential statistical tool that calculates the right-tail of the Student’s t-distribution. It is commonly used in hypothesis testing and confidence interval estimation when the sample size is small or the population variance is unknown. The function requires the t-value and degrees of freedom as inputs and returns the probability that a random variable from the t-distribution exceeds the specified t-value.
