Example sentences for: non-normal

How can you use “non-normal” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Non-normal distributions of divergence time estimates are often obtained in molecular clock studies involving many genes, or with genomic data [ 7 8 14 ] . Typically those distributions are right skewed, or have noticeable outliers on the right (older) side.

  • The current background subtraction algorithm may not take fully into account response factor-unrelated signals, therefore could further increase the non-normal component.

  • Although the t -test is robust to departures from normality and the Wilcoxon test does not depend on the normality assumption, the problem is that under non-normal situations the t -test may be too conservative, and hence, as with the Wilcoxon test, may have too low power, especially when the sample size is small, which is the case for most microarray experiments.

  • In those cases it would produce a similar result to the mean for normal distributions and would estimate the center of location with less bias than the mean for non-normal and contaminated distributions.

  • The reason for such non-normal distributions is unclear, but they are consistent with contamination from paralogous comparisons (those involving gene duplications), although other sources of bias have been proposed [ 15 ] . (The right-skewed distributions seen in some plots of evolutionary distances are different, because they have not been normalized by a calibration time).
