Question

34 multiple choice 2 points in the random sampling lab, why must plots be chosen randomly? to avoid bias and ensure an accurate population estimate to identify keystone species to maximize observed diversity to increase the number of samples collected

Explanation:

Random sampling helps avoid bias. When plots are chosen randomly, every part of the population (area being studied) has an equal chance of being selected. This leads to a more representative sample. A representative sample gives a more accurate population estimate. Identifying keystone species, maximizing observed diversity, or increasing sample number are not the main reasons for random plot - selection. Random selection's key role is in reducing bias for accurate estimates.

Answer:

To avoid bias and ensure an accurate population estimate
