Question
Numbeo is a crowd-sourced web site that gathers data on cities and countries around the world. Visitors to the site can add information on variables such as cost of living, traffic and crime. The data is searchable by city and country. For example, when we looked up Halifax, Canada, we discovered that a pair of jeans go for an average of $62.50. The range was $50 to $ 75. Add a summer dress from somewhere like Zara or H&M goes for an average of $48, with a range of $40 to $60. Numbeo also tells us that their Halifax data is based on contributions from 80 different people.
what kind of sample is this and what concerns might you have about this kind of sample?
Explanation / Answer
This is a Stratified Sample.
Reason a stratified sample is a mini-reproduction of the population. Before sampling, the population is divided into characteristics of importance for the research. Then the population is randomly sampled within each category or stratum.
