Altogether, PCA analysis indicated marked variability between datasets, raising the possibility that technical issues in the RNAseq samples or in their analysis compromised the Letourneau study.

Curation markedly increased the quality of the dataset, raising the average percentage identity between the human-chicken one-to-one orthologous pairs from 56%to73%3% [ 8].
Interestingly, the 'Oct-only' motif is also among the 17 motifs found by DREME in the Chen et al. Oct4 ChIP-seq dataset, raising the total number of identifiable motifs in that dataset to five (Table 1, column 5).
Statistical tests to assess whether a certain variable is associated with either the exposure, the outcome, or both, are typically insensitive in small datasets, but raising the significance level can reduce this problem [ 16].
The long-term storage of biological datasets has raised questions about efficient algorithms, formats, and methods for data entry, curation, and retrieval (Church et al. 2012; Goldman et al. 2013).
The Guardian Datablog in particular has pioneered the use of these open datasets and often raised awareness of important matters of public interest by analysing, visualising and mapping them.
However, it is when a university decides to combine these disparate data systems into one dataset that this raises some eyebrows.
Since a personalization element is limited in the datasets, the findings raise issues concerning the promise of democratic potentials of contemporary mediascapes.
Although concerns about the accuracy of routinely collected datasets have been raised, these are periodically audited.
