50 Students from the same school? Where was the control group? This is a
sample size of 1.

This sounds alot like the study that proves tornados are caused by paved
roads. As the number of miles of paved roads increased, so did ths number of
reported tornados.

I think the researchers from Mexico, Bosnia, Latvia and the Ivory Coast need
to work on their methods.

A team of researchers from Mexico, Bosnia, Latvia and the Ivory Coast
studied 50 children (ages 9-10 years old) who attended James Graham
Elementary in Newark, California. The researchers found that as
airplane noise around a school increased, students' reading
comprehension scores decreased.
