Worked example — results
| Result | Value | Unit |
|---|---|---|
| Mean moisture content w | 21.48 | % |
| Range (max − min) | 0.102 | % |
| Number of specimens | 3.00 |
- ✓ Range within tolerance
- ✓ Dry mass ≥ 30 g per specimen (fine soil guide)
Method, formulas and assumptions
- Mean moisture content w = AVERAGE([t.w]) = 21.483 %
- Range (max − min) = MAX([t.w])-MIN([t.w]) = 0.10162 %
- Number of specimens = COUNT([t.w]) = 3
