No significant difference in frequency of the different decay stages could be detected (Chi-2 = 3.56, p = 0.17, df = 2).
The same study used the high throughput possible with HREM to identify a significant difference in frequency of malformation between different mouse strain backgrounds.
Distinct Tol2 genome-wide targeting profiles in HEK 293 and HeLa cells seem to reflect their difference in frequency of targeting to different genomic contexts.
Similarly amongst infants there was no significant difference in frequency of defecation between different age categories (Myo-Khin et al., 1994).
The difference in frequency of each COG was calculated between TnLib/IMP enriched gene disruptions and the WT E. coli genome (Fig. 4).
First, meerkats showed no sex difference in frequency of play fighting (consistent with the optimal design argument, since both males and females fight to obtain the dominant breeding position in a group).
Why no difference in frequency of use of personal external information sources?
What variables might make a difference in frequency of use of personal external information sources?
There was no difference in frequency of use of personal external information sources based on SOP-visual, SOP-verbal, or fashion leadership.
The difference in frequency of association of the fusion proteins with ESFT is currently unexplained, and could conceivably reflect the relative frequency of the corresponding chromosomal breaks.
Another factor which can be taken into consideration is the difference in frequency of reported sexual harassment among men and women.
