The following article introduces you to the T.DIST.2T function - one of the functions in the statistical group is very popular in Excel.
Description: The function returns the two- tailed Student's t-distribution . Functions used in testing the hypothesis of small numbers of data sets. Support functions from Excel 2010 onwards.
Syntax: T.DIST.2T (x, deg_freedom)
Inside:
- x: Value used to evaluate the distribution, is a required parameter.
- deg_freedom: Number of degrees of freedom of the distribution, is a required parameter.
Attention:
- Any argument that is not a number -> the function returns the #VALUE! Error value
- If deg_freedom <1 -> the function returns the #NUM! Error value
- The minimum value of deg_freedom must be equal to 1.
- If x <0 -> the function returns the #NUM! Error value
For example:
Calculate the Student 2 t- tailed distribution as described in the following data table:
- In the cell to calculate, enter the formula : = T.DIST.2T (D6, D7)
- Press Enter -> 2 t Student distribution is:
- If the number of degrees of freedom is less than 1 -> the function returns the #NUM! Error value
- Where the value for distribution distribution is less than 0 -> the function returns the #NUM! Error value
Above are instructions and some specific examples when using T.DIST.2T function in Excel.
Good luck!
