TitleBetter sampling, more analyses, bigger laboratories?
AuthorsHutchinson TP
Year2005
TypeJournal Article
AbstractI'm a statistician. I don't know a mass spectrometer from a resonating horoscope. But it seems to me that: Many practitioners and researchers do not have an optimal balance between the various stages of their data collection; A better balance would involve them making more use of the fancy bits of kit back in the laboratory; and This should be of great interest to those who sell laboratory services or the fancy bits of kit. The key point is that the user typically wants (or should want) some idea of the accuracy of the results -the accuracy of the sample in representing the relevant population, that is, not merely the accuracy of the fancy bits of kit themselves. I am not making the familiar plea that an accurate estimate of a mean requires a large sample size. That's often true and important, but it's not my point. Rather, I am saying that a larger sample size will enable certain components of variability to be estimated that are vital for answering certain questions.
