Research is systematic and organized effort to investigate a specific problem that needs a solution. It also corrects human knowledge. A sample design is a definite plan for obtaining a sample from a given population. It refers to the technique or the procedure the researcher would adopt in selecting items for the sample. Sample design may lay down the number of items to be included in the sample ,the size of the sample. Sample design is determined before data are collected. There are many sample designs from which a researcher can choose. Some designs are relatively more precise and easier to apply than others. Researcher must select/prepare a sample design which should be reliable and appropriate for his research study. In Probability Sampling each item or element in universe has equal chance of being selected , It is called random/chance sampling. Each element of the population has known chance of being selected for the sample.
