2. What is sampling design? Sampling design is the method you use to choose your sample. There are several types of sampling designs, and they all serve as roadmaps for the selection of your survey sample. The objective of sampling design is to ensure that your selected sample allows you to generalize your findings to the entire population you’re targeting.

3. Keep in mind the following points when developing your survey design : Define the universe of your study: This is the set of objects you are studying. This could be the population of a city, the number of workers in a warehouse, or fans of a particular television show.

4. Consider your sampling unit: Will it be geographical, social, or individual Gather your sampling frame: This is the list of names from which your sample will be drawn.

5. Determine sample size: Use the equation above or our helpful sample size calculator . Factor in budgetary limitations: This will impact both the size and type of sample and may even lead you to use a non-probability sample.
