A t-Distribution Calculating System is a probability distribution calculation system that can solve a t-distribution calculation task (for a student's t-Distribution).
- AKA: Student's t-Distribution Calculator, T-distribution Algorithm, T-calculator.
- Context:
- It can be based on a t-tables.
- Example(s):
- An interactive online t-calculator such as:
- One based on on the scipy.stat functions[1]:
scipy.stat.t.pdf
,scipy.stat.t.cdf
andscipy.stat.t.interval
. - An Excel spreadsheet functions such as
TDIST
andTINV
. - …
- Counter-Example(s):
- See: Student's t-Distribution, One-Sample t-Test System, t-Table.

- Most statistical textbooks list t-distribution tables. Nowadays, the better way to a fully precise critical t value or a cumulative probability is the statistical function implemented in spreadsheets, or an interactive calculating web page. The relevant spreadsheet functions are
TDIST
andTINV
, while online calculating pages save troubles like positions of parameters or names of functions.
