Post 4 Sampling Strategies

Area Systematic Sampling:

  • Time: 12 hrs 37 min
  • Sampling error for most common: 11.5% (Eastern Hemlock) and 21.7% (Sweet Birch)
  • Sampling error for rarest: 90.5% (White Pine) and 100% (Striped Maple)

Area Random Sampling:

  • Time: 12 hrs 43 min
  • Sampling error for most common: 10% (Eastern Hemlock) and 17% (Sweet Birch)
  • Sampling error for rarest: 100% (White Pine and Striped Maple)

Area Haphazard Sampling:

  • Time: 12 hrs 36 min
  • Sampling error for most common: 20.6% (Eastern Hemlock) and 13.4% (Sweet Birch)
  • Sampling error for rarest: 50% (White Pine) and 66.9% (Striped Maple)

Haphazard Sampling had the fastest sampling time but they were all pretty close in time. For the most common species (Eastern Hemlock), the sampling error was lowest with Random Sampling and Systematic Sampling. For the second most common species (Sweet Birch), the sampling error was lowest in haphazard. For the least common species (White Pine and Striped Maple) the sampling errors were lowest in haphazard sampling. The accuracy of the sampling seems to decrease when the species is less abundant which is seen from the much larger sampling errors for rare species rather than common species. Haphazard sampling in this case seems like it was the most accurate because it sampled some of each species whereas systematic missed a rare species and random missed two rare species.
