The phrase "a realistic sample of" is correct and usable in written English.
It can be used when referring to a subset or representation of a larger group that accurately reflects its characteristics or qualities.
Example: "The study aimed to gather a realistic sample of the population to ensure the results were valid and applicable."
Alternatives: "an accurate representation of" or "a true reflection of".
The test material has to be a realistic sample of the actual data that belongs to the target application scenario.
Unfortunately, many datasets are not made publicly available; and those that are frequently used do not contain a realistic sample of degradation types targeting a specific application under study, or their limited size does not allow for statistically significant results.
First, CASP targets comprise a realistic sample of currently solved protein structures and exemplify the corresponding challenges for predictors.
Since all patients registered in the programme with a baseline fitness test were included, the participants represent a realistic sample of the population of people who are likely to access cardiac rehabilitation.
To simulate a realistic sample of novel human genome insertions, we sampled substrings of varying length from the set of insertion sequences reported in a novel insertion characterization study (Kidd et al., 2010), and inserted them to the transcript sequences at random exon breakpoints.
Our study addressed the question whether the assumption of different BWCs consistently influences O2Hb, HHb, tHb and rcStO2 readings in a realistic sample of clinically stable preterm infants using computations based on absolute coefficients μa and μs' determined by multi-distance FD-NIRS and the diffusion equation for homogeneous, semi-infinite media.
For example, in our simulated data set of 10,000 participants, a realistic sample size for large-scale genetic association studies, obtaining exposure data for approximately 20% of the full sample achieves maximum power when the first-stage R is greater than 0.015.
This improvement in the conformer acidity predictions for both ensembles reflects the benefit of a physically realistic sampling of the protein conformational distribution.
In fact, a major contribution of the paper is elucidating what the structure of future experiments should be to provide realistic samples of contact and disease dynamics for a given population.
To include some realistic sampling of species, the validation set for mycobacteria included the set Myc_Retro consisting of all mycobacterial (meaning positive MGIT culture) samples sent to the laboratories at the Oxford John Radcliffe Hospital between 2 June 2013 and 29 January 2014.
These data provide a realistic representative sampling of all ICU admissions in ANZ [ 24].
