Longitudinal Survey

Longitudinal Survey, or Trend Study is a study that covers a period of time. It is not a snapshot, like the surveys we have been conducting. The U.S. Department of Labor Bureau of Labor Statistics conducts various longitudinal surveys, and I came across one that was studying our age group. The study, called NLSY97, started with studying 9,000 males and females born from 1980-1984. The Bureau of Labor Statistics started surveying when the participants were ages 12-16. They now are surveyed annually to see the change in data. The purpose of this survey is to monitor the change from school to work and then into adulthood. They recieved some interesting data on high school transcript variations in PE courses, gifted courses, standardize testing scores, and number of absences when the group was is high school that I thought were interesting.

I bet that they are also running into complications collecting thier surveys just like our communications class has. Running into problems such as people dropping out of the survey, non-response survey, measurement error, and processing error are sometimes extremely hard to avoid. RYAN HERBS BLOG discusses different errors from survey. Dana's Blog is also touching on error with some good links.

"To live life expecting error, is to not live."
"error free is the way to be, oh and stay off drugs too."
Yea, i just made those up.
