Which technique had the fastest estimated sampling time?
The Systematic sampling method has the fastest sampling time at 12 hours and 6 minutes. Only around 30 minutes faster than the other two methods.
Compare the percentage error of the different strategies for the two most common and two rarest species. Did the accuracy change with species abundance?
The accuracy for the most abundant species seemed to be higher than for the least abundant species. In the systematic sampling method, the accuracy decreased as the abundance decreased. In the random sampling strategy, the accuracy was very poor despite the abundance although it does seem to decrease as abundance goes down. Finally, in the haphazard sampling, we see a similar trend of a decrease in accuracy as the abundance of a species decreases.
Was one sampling strategy more accurate than another?
The random sampling strategy was the most error prone method on average. This was followed by the haphazard method and finally, the systematic method was most accurate. Interestingly, during the random sampling phase, I did not sample any White Pine.
