Question

This Question: 1 pt 8 of 19 Identify the sampling techniques used, and discuss potential sources of bias (f any) Explain Soybeans are planted on a 53-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? A. Smple random sampling is used, sance each sample of soybean plants of the same amount has the same chance of berg selected O B. Cluster sampling is used, since the field is divided into subplots, a number of subplots are selected, and every soybean plant in the selected subplots is sampled O C. Converience sampling is used, since the soybean plants closest to the barn are sampled OD. Stratified sampling is used, since the feld 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 Certan sub lots may have more or fewer soybean plants than others Samples from these subplots may bias the overall sample B. It is possible that, due to sampling error, the sample will not be representative C. The sample only consists of the soybean plants that are easiest to reach This may not be representative of the etre population. D' There are no potential sources of bias Click to select your answerls)

Explanation / Answer

Stratified samplng is used as that entails dividing the plot into subplots and then samples taken from each subplot. The biases that exist are A and B as certain subplots may have fewer soyabeans and also due to sampling error, representative sample may not be picked.
