A personal trainer investigated the effects of operant conditioning using two separate groups of adult gym members:
Group 1: the trainer rewarded a group of members with digital achievement badges on their fitness tracker app in addition to the standard workout log.
Group 2: the trainer rewarded a different group of members with only the standard workout log.
After three weeks, the trainer calculated the average number of weekly workouts completed by the members in Group 1 and those in Group 2.
The results are shown in Table 1.
Table 1: Average weekly workout completion for Group 1 and Group 2
| Group 1 (App Badge) | Group 2 (No App Badge) |
