Marcus conducted an investigation into the effectiveness of a mindfulness smartphone app on reducing stress. He measured participants' self-reported stress levels on a scale of 1 to 10 (where 10 is extremely stressed) both before starting to use the app (Condition A) and after two weeks of daily app usage (Condition B).

Marcus's results are shown in Table 1 below.
