Formula Generator - T.INV.2T function
The T.INV.2T function calculates the inverse of the two-tailed TDIST function. It returns the critical value for a given probability and degrees of freedom in a two-tailed t-distribution. This function is commonly used in hypothesis testing and confidence interval calculations.How to generate an T.INV.2T formula using AI.
To obtain the T.INV.2T formula, you could ask the AI chatbot something like: "What is the formula in Excel to calculate the inverse of the t-distribution for a two-tailed test?"
T.INV.2T formula syntax.
The T.INV.2T function in Excel is used to calculate the inverse of the two-tailed Student's t-distribution. Its syntax is as follows: =T.INV.2T(probability, deg_freedom) - probability: This is the probability associated with the two-tailed t-distribution. It must be between 0 and 1. - deg_freedom: This represents the degrees of freedom for the t-distribution. It is the number of observations minus 1. The T.INV.2T function returns the value that corresponds to the specified probability and degrees of freedom in the two-tailed t-distribution. This value can be used for various statistical calculations and hypothesis testing in Excel.
Calculating Confidence Interval
Calculates the confidence interval for a given sample mean.
=T.INV.2T(alpha/2, n-1) * (standard_deviation / SQRT(n))
Hypothesis Testing
Performs a two-tailed t-test to determine if there is a significant difference between two sample means.
=T.INV.2T(alpha/2, n1+n2-2)
Estimating Sample Size
Estimates the required sample size for a given confidence level and margin of error.
