Question

The health of wild bighorn sheep is of concern to wildlife managers. To determine the health, wildlife managers want to trap and measure the weight, cortisol levels (a stress hormone) and examine the DNA to measure genetic diversity. For each of the following, identify the sampling method used or attempted and what (if any) bias might result.

c. Wildlife managers travel to each known region where bighorn sheep live and trap and release all sheep within each region. Measurements are taken on and DNA collected from each trapped sheep.

d. Randomly place 5 traps within each known major mountain range where bighorn sheep live. Measurements are taken on and DNA collected from each trapped sheep.

Explanation / Answer

C. Here all the sheeps are being trapped and released and their DNA are collected thus it's not sampling rather whole population data is collected here.

D. Here the sheeps are distributed into groups and from each group 5 are being randomly selected hence its a you're of cluster sampling.
