  1. Data Handling & AnalysisZO40302012-2013 Andrew Jackson a.jackson@tcd.ie

  2. Basic Data Organisation • Use Excel to input and organise your data • Each row is a different observation

  3. Propose an hypothesis • That the mass of brains of mammals (Mammalia) are different to the brains of birds (Aves) • Identify the Response Variable • Identify the Explanatory Variable(s)

  4. Calculate new response variable Explanatory Variable Response Variable

  5. How will we plot these data? Brain / body mass ratio Aves Mammalia

  6. Questions • Biological question • Does brain size differ between birds and mammals? • Data question • Is the mean ratio of brain to body mass different between the birds and mammals?
