Plan before you collect data

You need to

  1. Have a clear research question and
  2. Plan the experimental design a study

before you start the experiment analyse the data! So get assistance from a mentor or colleague, or look at a paper close to your study. Make sure that what you intend to do is correctly designed. Have you got a replicated and randomised design? have you looked at the greenhouse, or the field to see whether you need to block for a gradient in your environment.

If you plan well and early the whole experiment will be easy to manage. You write the analysis code ready for the data  collection phase. You can anticipate your method of analysis, and plan your reporting. Think of any pre-planned comparisons you may wish to make?
