The phrase "a poor sample" is correct and usable in written English.
It can be used when discussing the quality or representativeness of a sample in research, surveys, or any context where sampling is relevant.
Example: "The results of the study were inconclusive due to the fact that we were working with a poor sample of participants."
Alternatives: "a subpar sample" or "an inadequate sample."
No DNA sample gave an abnormally large number of discrepant genotypes as would be the case with a poor sample or array; however some SNPs performed poorly, independent of the redundancy in the probeset.
Furthermore, (iv) the decision to filter out poor samples can be made later, because a poor sample will not affect the processing of other samples.
After 2 hours, the bacteria will ferment the glucose and cells will lase giving a poor sample and in effect, poor diagnostics.
We can therefore reject the possibility that the negative γ-value is the result of a poor sampling artefact.
The pure-birth and birth-death models with taxon sampling are found to provide accurate rate estimates, although a poor sampling yields substantially wider 95% HPDs.
Large sample numbers and sophisticated analytical techniques, although important, should not be seen as a substitute for the collection of a representative sample and a poor sampling can be the dominant source of error in water quality data.
If the particle or vesicle concentration is to small, the probability of a particle having a fruitful interaction with the surface is decreased, leading to a poor sampling statistics.
We have shown that this critical depth was neither due to a spatial filtering of the dCV due to a limited FOV of the microscope nor due to a poor sampling of the small speckle grain by the camera pixels.
At 373 K, only few transitions to I and back to N were observed and the dwelling time in the I state was very small, indicating a poor sampling of this state.
Although other high-throughput experiments such as SAGE do introduce erroneous low-frequency tags, for EST data at such a poor sampling depth even those genes detected at low sampling frequency are most likely to be moderately and even abundantly expressed.
The apparent DAP band and LO phonon replica are consistent with a poorer sample quality and rougher surface morphology in the LT-32 sample.
