What type (name) of error is the "zero error" of the micrometer assuming it enters a calculation? What kind of errors of the procedural, systematic, and random errors could possibly occur while finding the mass of a burning candle by placing a candle on an electronic scale and lighting it...
Process control requires that data be gathered in samples. Discuss random sampling and systematic sampling and provide examples of each sampling method. Describe and compare internal and external validity. Be sure on include for each type: a definition, the critical issue it addre...
This study aims to understand tumor heterogeneity and its relation to BC lineage at a single-cell resolution. Chromatin accessibility, TF motif enrichment and their impact on the transcriptome reveal the structure of BC heterogeneity through integration of bulk-RNA/DNA sequencing, scRNA-seq, snRNA-se...
Specifically, they used random-effects meta-analysis, which assumes that results vary between studies not just from random error but also from true variation (ie, 'heterogeneity', from differences in study protocols, regions, etc). Next, they performed random-effects meta-regression to investigate ...
Firstly, the gene expression matrix was filtered on the bases of probe detection p value, and genes with a high number of missing values were removed (>70%). Subsequently, the missing values were replaced with random numbers coming from the 15th percentile, and data were normalized using ...
A phylogenetic tree was constructed with the aligned UGT1 protein sequences in MEGA 8.0 (http://www.megasoftware.net/) using the neighbor-joining method with the following parameters: Poisson correction, complete deletion, and bootstrapping (1000 replicates, random seed). Red indicates candidate ...
One tailed Fisher's exact test was used to calculate the p value for nonrandom association of mRna ensembles with a given pathway. Subcellular Protein Fractionation Dissociated DRG neurons were plated on porous membranes (3 μm pore diameter) and cultured for 3 d. After rinsing with PBS three...

Answer to: Define extraneous variable and confounding variable. Describe two methods used to prevent extraneous variables from becoming confounding...
32). e, STARR-seq signal enrichment over input in BRD4-AID cell line separated by strand for enhancers overlapping TATA-box promoters (N = 190), distal enhancers not overlapping promoters (N = 4917) and random inactive regions (negative control; N = 5151). Sense strand ...
