The phrase "a significantly different set" is correct and usable in written English.
You can use it when comparing two or more groups, items, or concepts that have notable differences in characteristics or attributes.
Example: "The study revealed a significantly different set of results when comparing the two experimental groups."
Alternatives: "a notably distinct group" or "a markedly different collection".
A joint deterministic stochastic protocol based on Monte Carlo simulations (MCS) was applied to the modelling of a medium size catchment using two significantly different sets of potential evapotranspiration (ETp) data, estimated through a Penman-based method.
In each city, there will be a short in-port race, requiring a significantly different skill set.
In the experiment, 100 × 100 × 15 mm cuboid samples made of 50CrV4 steel were subjected to laser hardening with significantly different sets of applied technological parameters (laser beam power, laser beam velocity) but still aiming at attaining a comparable maximum temperature on the sample surface.
Furthermore, empirical identification of amino acids that interact with the DNA by chemical shift perturbations in response to DNA titrations have yielded significantly different sets of candidate residues in two NMR studies [28], [30].
Altogether, these observations suggest that mutualism and parasitism are two distinct host-relationships supported by significantly different sets of functions.
The second method (Breassort) uses a Bayesian approach, together with multidimensional scaling and SPR, to identify the most frequent SPR operations that connect two significantly different sets of trees.
These results show that strains of the same species (CBS 513.88 and ATCC 1015) with near identical genomic content can use significantly different sets of enzymes to hydrolyze complex biomass.
The effect of gene and protein expression data in our approach is clearly observed, particularly leading to two significantly different sets of pathways depending upon whether this information is included or not.
