It can be used when discussing differences or changes in a particular variable or set of data.
Example: "The study revealed a substantial variability in the participants' responses to the survey questions."
Alternatives: "a significant variation in" or "a considerable difference in".
For the best performance of an e-nose system, the segments of an array should exhibit a substantial variability in their sensor properties.
Thus, the data obtained reveal a substantial variability in the NKG2 repertoire among NK cell subpopulations, which is likely to affect the sensitivity and reactivity towards the ligand HLA-E.
Conclusion: A substantial variability in LOS after complication-free coronary artery bypass graft surgery was determined predominantly by site per se, even after adjustment for disease severity, site type or location, and surgical and anesthetic practices.
Our findings show a substantial variability in the amount of recombination within and between dose groups with no clear correlation between tamoxifen dose and the number of marked cells.
Also, the BCH data are at a single nominal point in time but, due to the practicalities associated with imaging pediatric patients, there was a substantial variability in imaging time.
Many studies of human cortical architecture show that sensory and motoric fields have some relationship to the gross sulcal and gyral morphology, although a substantial variability in both size and location is observed [1 4].
Interestingly, even if the genetic diversity present in wild and primitive Pisum sativum accessions is larger than in the cultivar and breeding germplasm (Table 4), a substantial variability is retained in the cultivated pool.
However, there is a substantial variability among individuals in the level of TH that represents homeostasis, and the normal range of fluctuations for an individual is narrower than the normal range for a population.
Although a substantial variability has been reported in the jejunal mucosal microcirculation of pigs [29], multiple studies have confirmed the excellent reproducibility in the human sublingual area [4,5,26].
Similarly, both MMP2 and MMP9 mRNA levels showed a substantial variability with some peaks generally in mice of older age (Figure 3B and 3C, for MMP2 and MMP9 mRNA, respectively).
This is largely due a substantial variability of plasma MMP8 and MMP9 in patients without AAD, which leads to negligible specificity and positive predictive value of these markers.
