Market Research• Multi-Stage Sampling
– Sample selected from multi-stage sub-groups
– is a complex form of cluster sampling. – For example, you want to conduct a survey of
salespeople for a nationwide retail chain with stores all over the country.
– You could randomly select states, randomly select counties in each state, randomly select stores in each county, and randomly select salespeople in those stores.

Market Research• Multi-Stage Sampling
– Multistage Sampling is a sampling strategy (e.g., gathering participants for a study) used when conducting studies involving a very large population.
– The entire population is divided into naturally-occurring clusters and sub-clusters, from which the researcher randomly selects the sample.

Information:– Quantitative Information – based
on numbers – 56% of 18 year olds drink alcohol at least four times a week - doesn’t tell you why, when, how
– Qualitative Information – more detail – tells you why, when and how!
