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.
 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.
 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.
 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.
