Document Summary
The science triad: body of knowledge, process for learning, way of knowing (nature of science) Fact- concrete evidence, discrete observation, used to describe tested hypotheses. Hypothesis- something proposed to be true, testable, falsifiable statement. Theory- result of repeated testing, well supported explanation of natural phenomena. Law- widely accepted, science community agrees, doesn"t attempt to explain. Truth- unobservable, absolute state of clarity and accuracy. =given that that b occurs, probability of a. No way to measure entire population but can measure a sample. Rigorous way to generalize from sample to population. Statistics- gives a structured way to draw conclusions about a population from a set of data. P(a) = probability of a as an outcome. P(a)=p(a|b) x p(b)+ p(a|not b) x p(not b) Bayesian- calculate probability of each model given the data; model with highest probability is most likely. Frequentist- calculate probability of each model given a null model.
