An ergonomist investigated the impact of using an active under-desk balance board versus a standard static footrest on the concentration levels of remote administrative workers. She conducted an experiment with a sample of 10 participants obtained via opportunity sampling. In the baseline week, during daily 3-hour morning shifts, participants recorded the number of times they lost focus (e.g., checking social media, leaving their desk for non-essential tasks) while using a standard footrest. In the second week, the same participants used an active balance board during their shifts and recorded their focus-loss frequency. The data collected is presented below:
| Participant | Number of focus-loss instances during 3-hour shift | |
|---|---|---|
| Standard footrest | Active balance board | |
| A | 12 | 15 |
| B | 18 | 8 |
| C | 7 | 6 |
| D | 22 | 11 |
| E | 14 | 16 |
| F | 9 | 5 |
| G | 15 | 8 |
| H | 20 | 21 |
| I | 11 | 4 |
| J | 16 | 10 |
