Some market research is this type, which is why researchers often ask for your age: they are checking whether you will help them meet their What is Sample design in Research Methodology ? A sample design is made up of two elements.Random sampling from a finite population refers to that method of sample selection which gives each possible sample combination an equal probability of being picked up and each item in the entire population to have an equal chance of being included in the sample. Sample Design: Sample design refers to the plans and methods to be followed in se lecting sample from the target population and the estimation technique formula for computing the sample statistics. A stratified sample is a sampling technique in which the researcher divides the entire target population into different subgroups or strata, and then randomly selects the final subjects proportionally from the different strata. This type of sampling is used when the researcher wants to highlight specific subgroups within the population. A sample design is the framework, or road map, that serves as the basis for the selection of a survey sample and affects many other important aspects of a survey as well.
