Sentence examples for confounding variability from inspiring English sources

Experiments using quantitative real-time PCR to test hypotheses are limited by technical and biological variability; we seek to minimise sources of confounding variability through optimum use of biological and technical replicates.

Such confounding variability should also be taken into account in the model construction and evaluation, perhaps in some form of population stratified cross-validation.

A PCA-based approach was used to correct for confounding variability due to hidden factors in the gene expression data [ 85] as outlined in the Supplementary Methods (Additional file 8).

Similarly we excluded studies that reported on comorbidities (e.g. cancer and depression) in order to disentangle conclusions about depression treatment from interventions targeting other comorbidities, as these may have added confounding variability in the data presented.
