**Results***Calculated from: T_Test_Paired.csv using R.***Group A:** mean: 101.37, standard deviation: 23.96, standard error: 7.58

**Group B:** mean: 84.62, standard deviation: 10.78, standard error: 3.41

**Mean difference:** 16.75

**P-value:** 0.0150

**Degrees of freedom:** 9

**T-statistic:** 2.9973

**Written as a sentence**There was a significant difference between Group A and Group B (mean difference = 16.75), with a 95% confidence interval from 4.11 to 29.39; t (9) = 3.00, p < 0.05.**Test assumptions***Your data must have these characteristics for this test to be valid.*

1) The values in each group are normally distributed.

2) Values on the same row are from the same subject.

3) A minimum of ten samples is recommended.

*Note: the Welch's T-Test variant was used for this calculation.*
