Probability of Student's t Explanation and Tables

Program References

The data is a 2 column table of numbers. The columns are separated by white spaces (space or tab)

Column 1 is
- either t value for calculating probability from t. t must have a positive value
- or Probability value for calculating t from probability. Probability must have a value between 0 and 0.5

Column 2 is degrees of freedom. Common degrees of freedoms are
- For a single group of n, mean, and sd, df = n-1
- For comparing two means, df = n1+n2-2
- For Correlation Coefficient, df = n-2
