The phrase "a number of statistically" is not correct and seems incomplete in written English.
It could be used in a context where you are discussing statistical data or findings, but it requires additional information to be meaningful.
Example: "A number of statistically significant results were found in the study."
Alternatives: "several statistically" or "many statistically".
The chemical analyses showed a number of statistically significant differences, with the majority being within the ranges reported in the literature.
The authors are at their most titillating — and, unfortunately, their most smug — when they're playing shrink, attributing quite a number of statistically quantifiable sports phenomena to certain psychological concepts.
In two randomized, double-blind clinical trials comparing pinacidil with prazosin and with placebo in patients with hypertension, a number of statistically significant and potentially beneficial effects on blood lipids were detected in the patients taking pinacidil.
By applying these parameters we identified a number of statistically significant genes which were analyzed further for biological consequences of such changes.
However, despite the moderate sample size, we found a number of statistically significant group differences.
The analysis revealed a number of statistically significant functional terms (Supplementary Table S4).
A number of statistically-supported studies indicated that smaller blocks (< 1000 ft. long) and higher connectivity indices tend to generate more pedestrian movement (Krizek 2003; Cerin et al. 2007; Frank et al. 2005; Badland et al. 2008; Chin et al. 2007).
As such, a number of statistically-based kernel functions have been developed, each providing a mapping into a generic feature space that provides a reasonable approximation to the true feature space for a wide variety of problem domains.
A number of meaningful, statistically significant correlations were evident, giving support to the validity of the new scale.
Generally, each algorithm will make a different number of statistically significant predictions and a proper threshold should be established for subsequent reproducibility and accuracy calculations (see "Discussion" for more details).
Therefore, the main aim is to find a model which, with the use of a limited number of statistically important parameters, will be able to describe the essential features of the analyzed time series.
