- TTestPaired[ <List of Sample Data 1>, <List of Sample Data 2>, <Tail> ]
- Performs a paired t-test using the given lists of paired sample data. Tail has possible values "<", ">" , "≠" that determine the following alternative hypotheses:
- "<" = μ < 0
- ">" = μ > 0
- "≠" = μ ≠ 0
- ( μ is the mean paired difference of the population)
- Results are returned in list form as {Probabilty value, t-test statistic}.
- Example:
TTestPaired[{1, 2, 3, 4, 5}, {1, 1, 3, 5, 5}, "<"]yields {0.5, 0}.
