The phrase "a more direct test" is correct and usable in written English.
You can use it when referring to a test or assessment that is straightforward and focused, often implying that it is less complicated or indirect than other tests.
Example: "To evaluate the effectiveness of the new teaching method, we decided to conduct a more direct test rather than relying on subjective feedback."
Alternatives: "a simpler test" or "a straightforward assessment".
Test 2 is a more direct test for identifying positive selections in the foreground branch, and significant LRT from test 1 can be resulted from either positive selection or relaxed selective constraint in the foreground branch [ 46], however, the power of this method may be limited when sample size or divergence time is low [ 46].
Using a rocky shore example, I demonstrate that a response-ratio analysis gives a more direct test of the hypothesis that aggregation by limpets reduces desiccation.
In our most recent paper, "The Effect of Common Ownership on Profits: Evidence From the U.S. Banking Industry," we argue that looking at profits is a more direct test of the underlying theory.
Here we propose a more direct test of the observed correlation between mass accretion and ejection by using UV emission to detect accreting gas and centimeter emission to trace the jet while disentangling the influence of high-energy X-ray radiation from the star.
Or better, an animal model study combining antibiotic and perfusion data could provide a more direct test and might even provide an algorithm to predict antibiotic effect from blood perfusion.
Therefore, in a second experiment, we again examined effects of self-selection on first impressions, but using a more direct test: comparing trait judgments to images that had been explicitly chosen as most and least likely to be used as profile images for different network contexts (see "Profile Image Dataset" method).
We thank the reviewer for pointing out that this more direct test was absent from our study.
Thus, there is a need for more direct tests of the hypothesis.
Aside from the possibly confounding factor of color stimuli and the relatively short duration of the employed paradigms, notable limitations of the current study include the small patient sample of convenience and a failure to include manipulations allowing for more direct testing of dual-process model hypotheses.
These results provide a rationale for improvements in OspA-based vaccines and suggest possible designs for more direct tests of antibody protective levels in vaccinated individuals.
Experiments on the biological consequences of differences in pesticide distribution include testing differences in application equipment, differences in formulation, and more direct tests of the influence of droplet size, droplet number, or application volume on efficacy for insecticides, herbicides, or fungicides applied as atomized sprays.
