WebSep 28, 2024 · Short answer: A 2 × 2 table has 1 degree of freedom (df), and one odds ratio (OR) correspondingly. A 2 × 3 table has two df, and two ORs. In that case, the null hypothesis tested by Fisher's test can be formulated as both the ORs being equal to 1. You could calculate the ORs by splitting into two 2 × 2 tables, or simply by using a logistic ... WebThe Agilent 2100 bioanalyzer has provided a tool to more clearly evaluate each of the major components making up total RNA and to assess how they vary with source, time, and storage. However, the relationship between rRNA profile and mRNA integrity is still unclear. Certainly total RNA with a 28S:18S rRNA ratio of 2.0 denotes high quality.
