A researcher investigated the impact of two different intervention strategies on workplace productivity. Employees in Department A used a Guided Mindfulness App (Intervention X), while employees in Department B listened to curated Classical Music Playlists (Intervention Y) during their breaks.
| Percentage of employees reporting high productivity after Intervention X (Mindfulness App) | Percentage of employees reporting high productivity after Intervention Y (Classical Music Playlists) |
|---|---|
| 85% | 72% |
Three months later, the researcher conducted a follow-up study with the same employees in both departments over another two-week period to see if the productivity benefits persisted.
| Percentage of employees reporting high productivity after Intervention X (Mindfulness App) | Percentage of employees reporting high productivity after Intervention Y (Classical Music Playlists) |
|---|---|
| 78% | 35% |
The researcher considered the data from both the initial trial and the follow-up study (Table 1 and Table 2). What conclusion might they draw from both sets of results? Explain your answer.
