BIOL 101 Lecture Notes - Lecture 1: Cellular Respiration, Statistical Hypothesis Testing, Scientific Method
Document Summary
Scientific method (not linear) characteristics: observe a phenomenon collect evidence. Physically watch organisms, read papers: propose an explanation for it or make a hypothesis. Make a testable predication: conduct a critical experiment, draw conclusions and make revisions (everyone uses the scientific method all the time) A hypothesis a proposed explanation for a phenomenon: a good hypothesis leads to testable predictions. Example: the number of birds is decreasing because the number of cats is increasing. Iv: treatment/what you are changing in experiment: dv: what you are measuring. Additional aspects of good experimental design: sample size, replicates, more replication, the more accurate and more confident in results, example: vaccines, and autism. Controlling variables the attempt to minimize any differences between a control group and an experimental group other than the treatment itself does not have the independent variable. The phenomenon in which people respond favorably to any treatment.
