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:
  - http://stattrek.com/online-calculator/t-distribution.aspx
  - http://surfstat.anu.edu.au/surfstat-home/tables/t.php
- 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):
- P-Value
- Significance Level
See: Student's t-Distribution, One-Sample t-Test System, t-Table.

(Stattrek, 2017) ⇒ http://stattrek.com/online-calculator/t-distribution.aspx
- The t-distribution calculator makes it easy to compute cumulative probabilities, based on t statistics; or to compute t statistics, based on cumulative probabilities.

(Wikipedia, 2016) ⇒ http://en.wikipedia.org/wiki/Student's_t-distribution#Table_of_selected_values
- 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 and TINV, while online calculating pages save troubles like positions of parameters or names of functions.
