The phrase "availability sample" is correct and usable in written English.
It is typically used in research contexts to refer to a sample that is selected based on its availability rather than through random selection.
Example: "In this study, we used an availability sample of participants who were readily accessible to us during the research period."
Alternatives: "convenience sample" or "accessible sample".
Availability: Sample C++-code for optimal backtrace is available in the Supplementary Materials.
These datasets suffer from a bias in the information about binding loci availability, sample incompleteness and diverse sources of technical and biological noises.
However, several obstacles such as cost issues, 24-hour availability, sample preparation steps and diagnostic accuracy have to be significantly improved in many of the existing PCR assays.
The sample has to be viewed as an "availability" sample, and we cannot know for sure how representative the attendees were of the national student population.
Accordingly, investigators should choose the gender and method of blood draw that best fits their needs regarding anesthetic availability, sample volume, and frequency of sample collection, to be used consistently throughout the study.
It is true that this was a non-random, availability sample and that such samples can always be challenged on the basis that they lack representation and reflect the views only of a self-selected sample, in this case perhaps of the more satisfied clients.
The reason for using students in our study was the availability sampling technique.
With a view to record the seasonal plankton availability, samples were collected in early September 2010 and early March 2011.
Given availability, samples were chosen to reflect an early, midpoint, and late assessment during a participant's follow-up.
An availability sampling approach was used: one patient responded to an open letter sent to the National Kidney Federation website; all other patients were invited to participate in the study by hospital staff.
Sample size for brain regions (varied due to availability and sample quality) included 8 posterior hypothalami, 6 anterior hypothalami, 7 diagonal bands and 4 LCs.
