The phrase "a high effect size" is correct and usable in written English.
It is typically used in statistical or research contexts to describe the magnitude of a relationship or difference observed in data.
Example: "The study revealed a high effect size, indicating a strong relationship between the variables."
Alternatives: "a large effect size" or "a significant effect size".
We recorded a high effect size both in knowledge and total acceptance scores (Athanasiou et al. 2012).
GWAS finds common variants (with a population frequency down to 5%%) with relatively small effect size and requires a large number of unrelated cases to provide significant results, whereas exome sequencing and WGS might be more suitable in capturing rare variants with a high effect size by sequencing a small numbers of individuals (Fig. 1).
Furthermore, in the summary of all experiments the correlation between recycling pool size and number of neighbours had a high effect size (Cohens d of 4.76) [38].
Only associations with a high effect size (r ≥ 0.5) are presented.
This example shows that a high effect size does not necessarily indicates a good responsiveness.
These studies demonstrated a high effect size for outcome measures (d = 1.2 - 2.4).
Geometry, traditionally supported by visualization, showed a higher effect size (ES = 0.67) compared to algebra (ES = 0.61).
When contrasted with problem solving, learning supported by explorations produced a higher effect size of ES = 0.62 (as opposed to ES = 0.54 for problem solving).
The fractions of recycled polypropylene and rubberwood flour increased all the mechanical material properties; however, increasing one fraction must be balanced by decreasing the other, and the rubberwood flour fraction had a higher effect size.
All other loci show a higher effect size in anti-CCP positive RA.
These might be additional common variants with very limited effect size, or rare variants with a higher effect size.
