The phrase "a relatively weak correlation" is correct and usable in written English.
It can be used in contexts where you are discussing the strength of a relationship between two variables, often in statistical or research settings.
Example: "The study found a relatively weak correlation between exercise frequency and weight loss, suggesting that other factors may play a more significant role."
Alternatives: "a modest correlation" or "a slight correlation".
Inversion of the SGM allowed estimation of fractional shrub cover with a root mean square error (RMSE) of 0.03 but a relatively weak correlation (r2 = 0.19) with the reference data (shrub cover estimated from high resolution IKONOS panchromatic imagery).
However, a relatively weak correlation between the spectra and the measurements of salinized soil makes spectroscopy difficult to use in predicting areas at risk of salinization, especially for low and moderately saline soils.
The results illustrated that the errors of MLG have a relatively weak correlation with all the other benchmarks because it uses the label encoding scheme and multilabel KNN classification [58] instead of conventional regression methods used in other benchmarks.
When similar protein and mRNA ratios from all the samples in our data pooled together were plotted together (graph not shown), we observed a relatively weak correlation of 0.55.
Our study outlines a relatively weak correlation between the clinical and pathological diagnoses for acute and chronic pulpitides.
Individual COG phylogenetic profiles may only show a relatively weak correlation with a phenotype profile, even when the corresponding gene is essential for the phenotype.
Our finding also indirectly supports this view as we found triglyceride, HDL-C and WC to be strongly correlated with one another and a relatively weaker correlation for BP and FPG with other traits.
It was interesting to observe a negative (albeit relatively weak) correlation between staffing and frequency of events reported (Pearson r = -0.087) (See Table 3).
Thus, both fat mass and insulin resistance should be regarded as relative and dynamic features, and this could explain the relatively weak correlation between the two variables.
However, the relatively weak correlation indicates that movement as measured in a movement analysis and self-reported health status measure different aspects of the impact of hip dysplasia.
