Document Summary
Science is the systematic testing of hypotheses to build theory. Deductive reasoning: general premises to make specific predictions (if organisms are composed of cells, then humans must be composed of cells as well) Key: hypotheses can be about anything, so long as they are falsifiable. Information/observation question hypothesis prediction test of hypothesis. If hypothesis cannot be falsified, it does not prove that hypothesis. Biological variation is key to evolution by natural selection. Variation indicates that multiple measurements must be taken. Observing the variation data we can describe the central tendency (average), and the variation (range). Hypothesis can be true but no supporting evidence. Hypothesis could be false but you found supporting evidence. This evidence either supports or contradicts ones hypothesis. Discrete (integers); numbers of seeds per flower, number of species in a plot. Continuous (resolution limited by measurement tools); biomass, landscape. Types of data collected limits the hypothesis type you can test and the type of analysis you can perform.
