The systematic sampling technique had the fastest estimated time to sample of 10 hours and 27 minutes. The haphazard sampling technique has the slowest estimated time to sample of 10 hours and 44 minutes. The random sampling technique had an estimated time to sample of 10 hours and 42 minutes. I can conclude that the accuracy decreased completely with a decrease in species abundancy. I would say that random and haphazard are equally accurate and systematic is a little less accurate than those.
Percentage Error – Most Common Species:
Random: 4.6% for Red Maple and 20.8% for White Oak
Haphazard: 4.0% for Red Maple and 34.2% for White Oak
Systematic: 5.3% for Red Maple and 14.1% for White Oak
Percentage Error – Least Common Species:
Random: 100% for Yellow Birch and White Ash
Haphazard: 100% for Yellow Birch and 525% for White Ash
Systematic: 100% for Yellow Birch and White Ash
