The phrase "average variations in" is correct and usable in written English.
It can be used when discussing statistical data or measurements that reflect typical changes or differences within a set of values.
Example: "The study analyzed the average variations in temperature over the past decade to understand climate trends."
Alternatives: "mean fluctuations in" or "typical changes in".
For example, the seasonal average variations in the diurnal PM2.5 mass were predominately driven by the sulfate component.
Average variations in incidence rates for the 5-year periods were estimated using a Poisson regression, adjusted for age for each gender and location.
The average variations in all the species were significantly greater than those in 34 groups for the total 59 codons (P < 0.001 for all codons, using two-tailed t-test, see Table S4).
However, the average variation in the temporal variability should be measured from the trend (predicted price) rather than from the mean in the ordinary coefficient of variation.
While the healthy group had a mean estimated variation of 0.6-cm WC, the average variation in the burnout group was 2.4 cm.
The average variation in specimen moisture content (measured by mass) between the various testing days was about 0.033%, indicating negligible moisture loss during the ultrasonic measurements.
The use of PCA enhanced the best average classification accuracies of BP and SVM. Figure 3 shows the average variation in classification accuracies versus the number of principle components with respect to various classifiers.
For instance, in the first quarter of 1994, seasonally adjusted GDP grew 5.48%% and in 2002, after a brief decrease, there was a swift recovery in output and its average variation in absolute terms was of 3.53 %.
Overall, the average variation in CRC incidence rates between successive five-year periods was +1.9%[955%CI: +0.6; +3.2] in males and + 0.3%[955%CI: -1.1; +2.8] in females.
They essentially provide information on the average variation in time and space of the concentrations of contaminants in the considered area.
On repeated analysis by the same observer, the average variation in the anterior extent of Meyer's loop was 2 mm, and the maximum variability was 4 mm.
