The phrase "a much stronger correlation" is correct and usable in written English.
It can be used when discussing the relationship between two variables, indicating that the relationship is significantly more pronounced than in a previous comparison.
Example: "The study revealed a much stronger correlation between exercise frequency and mental health than previous research suggested."
Alternatives: "a significantly stronger relationship" or "a notably higher correlation".
There is a much stronger correlation of the glass transition temperatures with the fracture properties of asphalts.
We determined turbidity had a much stronger correlation to HgP (r2 = 0.78 0.98) as compared to specific discharge (r2 = 0.36 0.55), making it an effective high-frequency surrogate at each site.
A similar study conducted in 2008 by the same authors found a much stronger correlation.
When Shaman and Kohn performed a similar analysis using absolute humidity--which is easy to calculate if you know the temperature--they found a much stronger correlation.
As compared to the snowfall, there is a much stronger correlation between traffic volume and average daily temperature during winter months, which indicates that very low temperatures in the winter season can significantly affect traffic volume counts.
The effect of a partner's education on use of modern contraception is higher than that of the woman, and a much stronger correlation exists between household wealth and use of reproductive health inputs than expected.
Nevertheless, we did not expect a very much stronger correlation as the two indicators measure substantially different things; rhinometry is a biological parameter measuring nasal geometry whereas the CQ7 measures the subjective perception of air through the nasal cavities and the impact of NC on activities.
Given the absence of a strong impact of CpG[o/e] on GC*CpG in human and the much stronger correlation between equilibrium and current GC content in chicken than in human, the strong positive relationship between CpG[o/e] and GC*CpG found in chicken is likely caused by the transitive nature of correlations and of no biological relevance.
The NCI-financial, obtained by financial document filtering, exhibits much stronger correlation with the VIX compared to the NCI.
Much stronger correlation such as ρ = 0.947 and τ = 0.902 was obtained by solving MIP (11), as shown in Table 1.
This is consistent with the much stronger correlation of outdoor UFPs with coarse PM (r = 0.83) than with accumulation-mode PM (r = 0.44) [Supplemental Material, Table 1 (available online at http://www.ehponline.org/members/2008/11189/suppl.pdf)].
