That's part of the reason I sigh. I guess what happened was students
were put in a room for some time to fill out the questionnaire and return
it on-site.
Apparently, randomization, reliability, validity, etc are alien to
these people.

i'll be out of a damned job if all the surveys are as ``good'' as this one.
the typical non-response for telephone interviews is at least 15% so that's
why we need all the missing data and non-response adjustment techniques.
well. i guess they can give the kids some candies and keep them attentive for
a while.;)
further more, there is absolutely no need for them to have a sample of size
15,090 for this kind of purposes. they could have spent the money on other
things that are much more im
