Basic Data Organisation • Use Excel to input and organise your data • Each row is a different observation
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)
Calculate new response variable Explanatory Variable Response Variable
How will we plot these data? Brain / body mass ratio Aves Mammalia
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?
