**Written in sentences**There was a significant difference between Group A (mean = 24.39, s.d. = 6.17) and Group B (mean = 15.37, s.d. = 3.34); t (19) = 4.55, p < 0.001.**Test assumptions***Your data must have these characteristics for this test to be valid.*

1) The values in each group are normally distributed.

2) A minimum of ten samples is recommended.

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