I am a member of the Brent Teenage Pregnancy Partnership Board I keep my eyes open for articles that might have some relevance to the task of trying to reduce the number of teenage pregnancies. There is clearly also a connection with preventing STDs (sexually transmitted diseases) .
Today I came across this article with the headline:
"Quarter of U.S. teen girls have sex-related disease"
at the end on the 2nd page I read:
"The findings were based on data from 838 girls who took part in a nationally representative health survey in 2003 and 2004. They were tested for various STDs."
I have never studied statistical analysis, or really understood the principles of carrying out sound surveys etc. but apart from noting the fact that the survey is already 4 years out of date I have a gut feeling that 838 girls isn't a large enough sample.
p.s. I have made a small effort to find the original report but without success
