BIOB50H3 Lecture Notes - Lecture 2: Quantitative Research, Scientific Control, Design Of Experiments
Document Summary
Scientific method a series of steps that is science. Don"t ever want the process to end because you want more questions to arise. Ecologists develop hypothesis that they see in nature incredibly complex. Concept: ecologists evaluate competing hypothesis about natural systems with experiments, observations, and model. Experiments are the most robust ways of generating questions and coming up with more observations. Observational studies in the field to affect results. Why do we replicate? goes back to sample size cant just base our observations on one affect our observations there are factors we cant account for. Ecologists use several methods to answer questions about the natural absence. We need to assign treatment at random world . (cid:884). experiments in the field exclude things to see what would happen in its. Experimental design fundamentally important aspects we have to stay true. Why do we randomize? don"t want other factors such as environment to.
