Purpose
- to conduct the "analyze" step of the data life cycle for a DNA microarray dataset.
- to develop an intuition about what different p-value cut-offs mean.
- to keep a detailed electronic laboratory notebook to facilitate reproducible research.
- to revisit the "Deception at Duke" case with new insights because you have analyzed your own dataset.
Methods/Results
- T test: is this gene expression change significantly different than zero at a time point?
- p>0.05 5%
- probability that you would have seen at least this big of a change by chance.
- ANOVA: is the gene expression significantly different than zero at any time point?
- Values below 0.25 should be considered to be a gene with no change in expression
