The phrase "average frequency of approximately" is correct and usable in written English.
It can be used when discussing statistical data or measurements that indicate a typical occurrence rate within a certain range.
Example: "The average frequency of approximately 50 Hz was recorded during the experiment."
Alternatives: "mean frequency of about" or "typical frequency of roughly".
The bi-alleleic inactivation of the RB1 gene has also been detected in sporadic human cancers of a variety of tissue origins at an average frequency of approximately 10% (COSMIC database at the Sanger Genome Center).
With the above constraints we found 100,514 IRs in the S. cerevisiae genome, an average frequency of approximately one every 120 bp.
The formation of a domesticated derivative, BR-S, of the wild S. cerevisiae BR-F strain on a non-fermentable medium occurs efficiently with an average frequency of approximately 2-3% [ 13].
From July 1 , 1995 until June 30 , 2001 the average frequency of PNSP carriers has been stable, approximately 7.4% (2,750 PNSP/34,745 pneumococci).
Noting that gait and heartbeat have similar frequencies, the period of the sine function representing a realistic gait has been chosen to approximately match the average frequency of the blood pressure data P t), and the amplitudes in the exponent and of the sine are motivated by anticipated signal-to-noise ratios of 5%%.
The average frequency of SNPs in the unigene sequences is 0.67%, or approximately 1 SNP per 1.5 kbp.
The average frequency of donut-shaped nuclei was 7% on day 4 of FTI treatment and had increased to approximately 35% by day 9.
Differentiated cells from three FSHD donors showed an almost 50 times difference in average frequency of DUX4-FL expression, with the frequency of DUX4-FL-positive nuclei per 1,000 nuclei in myosin-expressing cells ranging from approximately 0.1 (for 07Abic cultures) to approximately 4.7 (for 17Adel cultures) (Table 1).
We set the origin generation of the favored allele for each model to produce an average allele frequency of approximately 0.5, which met our goal of providing coverage for allele frequencies between 0.2 and 0.8.
This reflects an average HbA1c testing frequency of approximately twice per year.
In other recombinases, R4, TP901-1, Bxb1 integrases and FLPe showed average recombination frequencies of approximately 82.4, 39.3, 94.1 and 17.2%, respectively (Fig. 2C).
