- is the numeric value to find the distribution.
- is the degrees of freedom.
- is the number of tails.
- TDIST(),returns the Student t-distribution.
- This function gives the value of the T-Distribution.
- It is the continuous probability distributions.
- The T-Distribution is also called Students T-Distribution.
- This is the symmetric distribution like the Normal Distribution.
- It is used when making inferences about a population mean when the population standard deviation is not known.
- In , is the numeric value to find the value of the distribution.
- is the integer which is indicating the number of degrees of freedom and is indicating the number of distribution tails.
- Suppose Tail=1, then this distribution is One-Tailed Distribution and Tail=2, then this is Two-Tailed Distribution.
- Also Tail=1, then it is calculated as , where is a random variable that follows the T-Distribution.
- And Tail=2, then it is calculated as .
- This function will return the result as error
1. Any one of the argument is non-numeric. 2. DegreeOfFreedom<1 and Number<0. When we are giving DegreeOfFreedom and Tail as a decimals, then it is changing in to integers.
