The phrase "a large effect was" is correct and usable in written English.
It can be used when discussing the impact or influence of something in a specific context, often in scientific or analytical writing.
Example: "In the study, it was found that a large effect was observed in the participants' performance after the intervention."
Alternatives: "a significant impact was" or "a considerable effect was".
A rather small, non-significant effect was found for the system by which information was provided, whereas a large effect was found for traffic density on mean driving speed (F 1,22) = 12.2, p < 0.002).
Such a large effect was similar to that observed in SM/Ch mixed monolayers (Table 2).
In contrast, a large, effect was detected when considering the number of cats that reduced spraying by week four of treatment in comparison to baseline.
Thus a large effect was seen with the introduction of 50% non-targets belonging to the same superordinate category with a false alarm rate increase of 7.8% and a median RT increase of 64 ms. Further increase (from 50 to 100%) just strengthened this effect with an additional increase in false alarms and median RT (2.9%, 25 ms).
A large effect was seen for having respiratory symptoms that improved away from the building.
A large effect was also seen for the inclusion of any type of specialist (epidemiologist/clinical trials methodologist or biostatistician).
All factors in groups found to have a large effect are then studied in a second stage of experiments.
The QTLs with a large effect are also illustrated on the molecular linkage map (Fig. 1 based on E1 and Fig. 2 based on E2 and E3).
Such a large effect is surprising, given that the two carbon atoms are chemically equivalent.
These results show that more QTL with a large effect were fixed with BL than with RR, as expected.
Significant interactive effects are typically detected when the opposite response pattern is seen across gender, or when a large effect is present in one gender and a small effect is present in the other.
