We employed scan sampling (developed by Altmann 1974) for the observations; sequentially observing individual students.
For the observations, structured sheets were used on which the observers noted activities and contacts of the observed employees.
Previous animal studies could provide possible explanatory mechanisms for the observations made in this clinical observational study.
They don't appreciate the exposure, don't care for the observations, don't like The New York Times.
In a bid for skeptical rigor, the team has sought nonbiological explanations but has concluded that none can account for the observations.
Rather, the matter is whether, given our current state of knowledge, the most parsimonious and economical explanation for the observations reported is that the material is of extraterrestrial origin.
Limited evidence means that an association has been observed between exposure to the agent and cancer, but that other explanations for the observations - technically termed chance, bias or confounding - could not be ruled out.
Dr. Gleason repeatedly responded in the fashion of other scientists whose findings have gone viral: I am responsible for the observations, not the spin.
Possible reasons for the observations are discussed.
For the observations from geomagnetic observatories, r = a approximately.
Finally, 22 studies were included for the observations (Table 1).
