# "Terminology on Data Sampling"

Hi

simple question:

I have a scenario where i use cluster analysis to sample a set of data into different groups of homogenous entities. Then i extract one entity of each group as a representative. What is the terminology on that? I would call it something like Data Sampling, but googling data sampling wasn much successfull... For example "sampling" (wikipedia) seems to be concentrated on investigation on populations and such.

However, searching in this forum i think that sampling might nevertheless what i am looking for.I would appreciate any help on the terminology and also if somebody could advise some literatur on that topic.

greetings

20Contributor II63Contributor IIQuota is a subset of Stratified, but it makes sure that the sample proportions are similar to the population proportions of groups.

20Contributor IIPopulation is not the only kind of data that needs to be analysed.. I am a littled bit puzzled about that..
