Give a simple definition and an example of simple random, stratified random, cluster, and systematic probability sampling strategies.
Simple random– strong representativeness of the target population that increases with
sample size
Stratifies random– strong representativeness of the target population that increases
with control of stratified. Variables are commonly used for stratification such as age,
race, gender, diagnosis
Cluster- less representative of the target population than simple random sampling,
develops a sampling frame that includes a list of all the states, cities, institutions, or
organizations with elements of the identified population can be linked
Systematic– less representative of the target population, selecting the kth individua
