TDIST(Number,DegreeOfFreedom,Tail),
- is the numeric value to find the distribution.
- is the degrees of freedom.
- is the number of tails.
- TDIST(),returns the Student t-distribution.
is the numeric value to find the distribution.
is the degrees of freedom.
is the number of tails.
Description
- 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
, 
, where 
is a random variable that follows the T-Distribution.
. 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.
Examples
- =TDIST(1.82,55,1) = 0.037101192599
- =TDIST(1.82,55,2) = 0.074202385199
- =TDIST(5.9812,75,1)= 3.50350792266e-8
- =TDIST(5.9812,75,2) = 7.007015845328e-8
- =TDIST(2.4579,20.4,1) = 0.011612360861779858
- =TDIST(2.4579,20.4,1.2) = 0.011612360861779858
