The fastest sampling technique was systematic sampling at 5 hours and 3 minutes. The second fastest is random sampling with 5 hours and 16 minutes, and one-minute longer is haphazard sampling. When comparing the percent error for the hemlock the highest percent error was found in the random sampling technique. The highest percent error for sweet birth was also found in the random sampling technique. When comparing the least common species of the chestnut oak it had the highest percent error in the systematic sampling technique. And finally, the red maple has the highest error in the haphazard technique. With wanting the percent error to be as low as possible the random sampling seemed to contain the most error (24.3-95.74). Where haphazard had the least error (4.23 – 93).
- Random
- Total quadrants = 10
- Area sampled = 1000sq.m
- Species sampled = 5
- Total specimens’ samples = 122
- Quadrant sampled = 10 @ 30 min = 300min. distance travelled = 1248m @ 3mph = 16 min and total time = 5hr and 16 min.
- Percent error
- 640-469.9/469.9*100 = 36% (most common – hemlock )
- 230-117.5/117.5*100 = 95.74% (most common – birch )
- 120-87.5/87.5*100 = 37.14% (least common – oak)
- 90-118.9/118.9*100 = 24.3% (least common – maple)
