stratified sampling
Not much of a discussion here, is it? — Rickyrab | Talk 13:17, 14 May 2006 (UTC)
No, but maths sure is fun fun fun.
The real-world example below does seem correct:
A real-world example of using stratified sampling would be for a US political survey. If we wanted the respondents to reflect the diversity of the population of the United States, the researcher would specifically seek to include participants of various minority groups such as race or religion, based on their proportionality to the total population as mentioned above. A stratified survey could thus claim to be more representative of the US population than a survey of simple random sampling or systematic sampling.
The reason is because old polls used to have these quotas for religions and income, etc, and the accuracy of these polls were far worse than those from Gallop using simple random sampling. Using simple random sampling with sufficient sample sizes results in a representative sample.
Shouldn't the title be change to "Stratified sample" to refelct the article "Simple random sample"?
