Explanation:
Detailed explanation-1: -Cluster sampling is used, since the field is divided into subplots, a number of subplots are selected, and every soybeanplant in the selected subplots is sampled.
Detailed explanation-2: -Four main methods include: 1) simple random, 2) stratified random, 3) cluster, and 4) systematic. Non-probability sampling – the elements that make up the sample, are selected by nonrandom methods.
Detailed explanation-3: -A simple random sample is used to represent the entire data population and randomly selects individuals from the population without any other consideration. A stratified random sample, on the other hand, first divides the population into smaller groups, or strata, based on shared characteristics.
