t Test for Paired Measurements
Test whether average difference inside measurement pairs be zero.
Your numbers
t test statistic value
Pair positions must refer to the same unit or person; observations across different pairs must dey independent.

Formula
Apply one-sample t test to di differences inside each pair.
Test whether average difference inside measurement pairs be zero.
Example wey show the calculation
- Measurement wey come first
- 8, 9, 10, 11, 12
- Second measurement wey pair with first
- 7, 7, 8, 9, 9

- Di degrees of freedom
- 4
- Two-sided p-value
- 0.00319820215234
- Average difference: first measurement minus second
- 2
Where e fit work and limits
Pair positions must refer to the same unit or person; observations across different pairs must dey independent.
We check inputs for missing values and allowed ranges. Result wey pass the finite numeric range no go show. Rounding affect wetin display, while calculation use the model numeric precision.
Check your units and assumptions before you rely on result. Changing label no convert currency or physical unit.
