Returns the t distribution of the students. T-distributions are used for hypothesis testing of small sample data sets. This function can be used instead of the critical value table of the T-distribution.
grammar
TDIST(x,degrees_freedom,tails)
X is used to calculate the value of the distribution.
Degrees_freedom An integer representing the number of degrees of freedom.
Tails specifies whether the returned distribution function is single-tailed or double-tailed.
If tails = 1, the function TDIST returns a single-tailed distribution. If tails = 2, the function TDIST returns a two-tailed distribution.
Instructions
■ If any of the arguments is non-numeric, TDIST returns the #VALUE! Error value. .
■ TDIST returns the #NUM! Error value if any of the following occurs: .
- degrees_freedom < 1
- tails are not 1 or 2
3, x < 0
■ Parameters degrees_freedom and tails will be rounded off.
■ If tails = 1, the formula for calculating TDIST is TDIST = P(X > x), where X is a random variable that follows a t distribution.
■ If tails = 2, the formula for calculating TDIST is TDIST = P(|X| > x) = P(X > x or X < -x).
■ Because it’s not allowed. 0, when x < At 0, you use TDIST,
It should be noted that TDIST(-x,df,1) = 1 – TDIST(x,df,1) = P(x > – x) and TDIST (-x, df, 2) = TDIST (x df, 2) = P (x | | & gt; x).
