Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain. Alfalfa is planted on a 56-acre field. The field is divided into one-acre subplots. A sample is taken from each subplot to estimate the harvest. What type of sampling is used? O A. Convenience sampling is used, since the alfalfa plants closest to the barn are sampled. B. Simple random sampling is used, since each sample of alfalfa plants of the same amount has the same chance of being selected. C. Cluster sampling is used, since the field is divided into subplots, a number of subplots are selected, and every alfalfa plant in the selected subplots is sampled. D. Stratified sampling is used, since the field is divided into subplots and a random sample is taken from each subplot. What potential sources of bias are present, if any? Select all that apply. A. It is possible that, due to sampling error, the sample will not be representative. B. The sample only consists of the alfalfa plants that are easiest to reach. This may not be representative of the entire population. C. Certain subplots may have more or fewer alfalfa plants than others. Samples from these subplots may bias the overall sample. D. There are no potential sources of bias.

Transcribed Image Text:Identify the sampling techniques used, and discuss potential sources of bias (if any). Explain.
Alfalfa is planted on a 56-acre field. The field is divided into one-acre subplots. A sample is taken from each subplot to estimate the harvest.
What type of sampling is used?
O A. Convenience sampling is used, since the alfalfa plants closest to the barn are sampled.
O B. Simple random sampling is used, since each sample of alfalfa plants of the same amount has the same chance of being selected.
O C. Cluster sampling is used, since the field is divided into subplots, a number of subplots are selected, and every alfalfa plant in the selected subplots is sampled.
O D. Stratified sampling is used, since the field is divided into subplots and a random sample is taken from each subplot.
What potential sources of bias are present, if any? Select all that apply.
O A. It is possible that, due to sampling error, the sample will not be representative.
O B. The sample only consists of the alfalfa plants that are easiest to reach. This may not be representative of the entire population.
Certain subplots may have more or fewer alfalfa plants than others. Samples from these subplots may bias the overall sample.
O C.
O D. There are no potential sources of bias.
