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`

and`scipy.stat.t.interval`

. - An Excel spreadsheet functions such as
`TDIST`

and`TINV`

.

**Counter-Example(s):****See:**Student's t-Distribution, One-Sample t-Test System, t-Table.

*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`

and`TINV`

, while online calculating pages save troubles like positions of parameters or names of functions.
