Nine out of 10 urine samples from people in Malta contained traces of

The results in Malta are mirrored in results across Europe – with 45 per
cent of samples from the 10 volunteers in each of the18 countries found
to contain traces of the chemical.

Do you really believe that 10 volunteers is a valid sample size?

That reads as 10*18=180 volunteers.


Because of the small sample, lifestyle conditions will not form any type
of conclusion.

Blindingly obvious. The study is ********.

Not quite. It is sufficient to try to get funding for a larger study.
(Assuming of course that there was no significant bias when selecting
the volunteers).

No point in being concerned, yet, unless you are a Daily Wail reader.


That Expresses my attitude as well.
