Datum: a single measurement or observation and is commonly called a score or raw score: statistics, science, and observations. Four canons of science: determinism: universe is orderly, events are meaningful, with systematics causes. 5: theories: statements about the causal relations between two or more variables, variables: a characteristic or condition that changes or has different values for different individuals, empiricism: making theories based on observations, parsimony aka. Occam"s razor: when theories are equally good at explaining observations, then choose the one with fewest assumptions, or the simpler one: testability: confirmable or falsifiable using available research techniques. Statistics: the science of gaining insight from data through mathematical procedures. Descriptive statistics: statistical procedures used to summarize, organize, and simplify data.
