“One way to
ruin an otherwise well-conceived survey is to use a convenience
sample rather than one which is based on a probability design” (Ferber
et al, 1980). Do you have the right sampling design for your study?
This course introduces participants to what survey sampling is,
why it is important, and how it is implemented. It focuses on the
practical aspects as well as a bit of the maths. Content includes:
- types of samples (probability versus non-probability)
-
how to construct a “sampling frame”
- types of probability samples (e.g., simple random, systematic,
stratified, multi-stage clustered, unequal probabilities of
selection)
-
what “sampling error” is
- the role of sampling error in confidence intervals
- how to determine sample size
- a discussion of the effects of different types of
sample designs on confidence intervals
- an introduction to weighting.
Participants need to bring a calculator with a square root function
