First compute the mean of the ten measurements:
12 + 12 + 11 + 10 + 8 + 9 + 9 + 11 + 12 + 9 = 103
Mean = 103 / 10 = 10.3
Which activity it represents:
- Without a list of labeled activities, I can only compare to the other samples: Sample 1 has the lowest average (10.3) and a small spread (values 8–12), so it likely corresponds to the least active/lowest-intensity activity (for example: sitting or standing).
- Rationale: lower mean and low variability suggest consistently low activity levels; higher-intensity activities would produce larger average values and/or greater variation.
12 + 12 + 11 + 10 + 8 + 9 + 9 + 11 + 12 + 9 = 103
Mean = 103 / 10 = 10.3
