What are main types of sampling?
Probabalistic ond non-probabalistic
Several examples of non-probobalistic sampling?
Convenience sampling, quota sampling.
What is convenience sampling?
Samples are taken from population at a specific time and place.
What is quota sampling?
Samples are taken same way as at convenience sampling, but with difference in time
Name several examples of simple probabalistic sampling?
Simple random, systematic, stratified and cluster
How goes simple random sampling?
We just pick some units within population and take them.
How to perform systematic sampling?
Order sampling frame, randomly choose first unit of sampling, but all other units should be chosen according to some pattern - each fifths for example
What actions we need to perform stratum sampling?
We find some criteria within sampling frame, according to which we can create stratums - groups of units, that are alike each other. After that we randomly pick units within each stratum.
How to do cluster sampling?
We also create groups from samling frame units, but units within them should be defferent to each other (heterogenic) and then we ask each unit within cluster.
