BIOL2022 L12 The EXPERIMENTAL RESEARCH PROCESS; KEY ELEMENTS

Description

Module 2, Lecture 1 • Research process: o Doing experimental biological research:  Clear process  Clear structure o Writing reports, theses, papers  Similar structure o Role of stats?  Summarise data, patterns Are patterns “real”? Important, but just a part • Key elements: o Types of variables o Unit of replication o Limits of inference (statistical vs biological) o Strength of evidence o Parametric vs non-parametric stats
