Two groups of university students participated in a study evaluating two different stress-reduction interventions. One group used a daily Mindfulness App for six weeks, while the second group attended a weekly Time-Management Seminar.
All participants completed a stress self-assessment scale (scored from 1 to 10, where 10 indicates extremely high stress) at the start (week 0) and at the end (week 6) of the program.
Sketch and label a bar chart to illustrate these data.
