The phrase "a small correlation of" is correct and usable in written English.
It can be used when discussing the relationship or association between two variables, particularly in statistical or research contexts.
Example: "The study revealed a small correlation of 0.2 between exercise frequency and overall health."
Alternatives: "a slight correlation of" or "a minor correlation of".
Additionally, one study [21] reported a small correlation of motor performance with measures of agonist (rz = 0.36, r = 0.347, R2 = 12%) and antagonist (rz = 0.02, r = 0.015, R2 = 0%) EMG duration.
This indicates that there seems to be only a small correlation of the centre variable with the other explanatory variables.
A small correlation of 0.14 (p = 0.00515) between the optical densities of the same serum samples in indirect IgG SBV ELISA and in commercial ELISA was observed.
PHNs perception of frailty had a small correlation with risk of death (r = 0.21), but not institutionalisation (r = 0.07) or hospitalisation, (r = 0.04).
Regarding the proportional hazards assumption, Hollaender noted that assuming a linear risk function, a small correlation value rho of 0.147 was obtained [ 20].
We found that (i) peer judgements do not significantly correlate with the degree of interdisciplinarity; (ii) only elementary bibliometric indicators correlate negatively, but (iii) 'advanced' indicators do not correlate with the degree of interdisciplinarity, except a small correlation in the case of large programs.
Color conversion is a signal-processing technique for the transformation of the color representation coordinates into another coordinate system where some of the color axes comprise a small correlation, and the application of signal-processing functions can reduce the incidence of processing errors [30].
CR cervical resistivity, AUC Area Under the ROC Curve, LR Likelihood ratio, PPV positive predictive value, NPV negative predictive value, ** P < 0.01 Cervical resistivity, at each of the 4 frequencies between 9.8 and 78.1 kHz showed a small correlation with the duration of labour in women who achieved vaginal delivery whilst the Bishop score did not (Table 5).
Third, though there was a small correlation between the amplitude of FRET ratio changes and calcium transients, there was a large variability in FRET ratio changes for a given calcium transient amplitude (Figure 1E).
In contrast, a prospective Japanese study including 25 872 men and 33 919 women, aged 45 75 years, with no history of diabetes, demonstrated only a small correlation in men after 5 years of observation.
Cohen [33] claims that it is in the superior limit of a small correlation.
